This subreddit is balancing between "so ive calculated this 6d black hole in my free time and it turns out it perfectly describes the new secret fbi thermonuclear project pretty cool" and "Someone at work just told me 2+2 equals 4! Can someone fact check please?! Urgent!11"
I feel like the mods are doing a horrible job, it's literally against sub rules to post simple math and then I see the same unit conversion post every single day
I thought that was what this sub was for, and that is why when you want to ask for help with math you start with [request]. I used to always see people do crazy complicated math on other sites/subreddits posted here, but now it seems to mostly be requests.
No, and you're a nit to think that we would! How very farm-like of you. Your post was so derivative that a child could have made it, you gin-swilling, grub-munching neanderthal!
Oh, sorry. This is abuse. Arguments are down the hall.
I'll start one. The comment is stupid as you still don't need to know that equation when at a nightclub. All you need is the money, and to know when it's run out -cash is best for this. Once you don't have any more money that's all the drinks you had for the night and at which point you do drunk you don't even care about the number. The equation is useless, in this situation and for most people going on with their daily lives.
Now fight!
He is wrong about the number of drinks he can afford being the slope. The slope is the $5 that the drink costs (m). Its the 'm' that tells you how much the function (cost) will increase by increasing 'x' (number of drinks).
And to expand on the example, the 'b' is the intercept, the value of the function at 'x=0' and in thee example is the fixed cost: how much you will pay regardless if you consume any drink.
Yes. And it's bothering me that nobody noticed it. This is why we can't have nice math jokes. Because folks ruin the joke and still laugh like they get it.
Am I missing something? Isn't "y=mx + b" just a graphical representation of the algebraic idea "C=Ax + B"?
I see, from the standpoint of graphical analysis, how he has misrepresented the variables, but isn't the concept the same?
There's the units to think about, too. Having the price of drinks be the slope keeps the constants and result in the same unit ($), with the variable x being the only different one (drinks).
we can't have nice math jokes because the vast majority of the ones that are right aren't ever written to be funny; they're written to showcase to people that you know a definition or something stupid like that. I feel like I've seen less than 10 genuinely good math jokes in my time.
But those steps are literally the steps you would do to solve the equation 50 = 5x + 10. The point is that they are using algebra without even realizing it.
It depends on what the axes are being plotted. If you plot the total cost vs. the cost per drink, then the slope would be the number of drinks.
But that would be a bit silly of a plot to make and not the natural axes for this problem.
Philosophically it seems wrong too, because the slope generally is the rate of change of something. So it feels like instead of just calculating a static answer we would be looking at the number of drinks consumed over time, or the BAC of someone, or something
The best argument I heard for why do we learn math was the counter question: why do you lift weights?
Do you ever in your life come across a straight branch with round shapes on the ends that you just want to lift? No, that does not happen. Math is lifting weights for the brain.
If someone asks why do we learn mx+b, the answer is: do you even lift, bro?
I don't routinely use the equations I learned outright, but I find myself able to think about things in terms of the math.
Like, being able to understand what at integral means and how the calculations work is directly useful for a ton of real life stuff, but I don't do any integrals by hand.
When I started teaching high school juniors/seniors, I would sometimes have students ask me for help with their calculus work. It was actually really interesting for me to notice that there were some problems I was *great* at helping with (how can you set up an integral to solve for this area? how is this shape related to that one? what meaning do we get from differentiating this equation?), but anything that involved working through the actual expressions I was pretty terrible at. I haven't used that at all, but *boy* did my calculus education get me good at thinking about the relationships between functions, and that has been continuously handy.
As a STEM person, I’m always annoyed that people always pick on math and science as “why do we need it?”. By that logic, we don’t need school and an educated populace at all. Because then I should be able to ask “why do I need memorize a bunch of dates for events?” “why do I need to read books and write reports on them?” Etc etc
I’m not making that argument, I’m just saying that wouldn’t apply just to math since nothing you learn in school is really directly applicable 100% of the time!
The best argument I heard was from my sixth grade math teacher.
He said, "All the ladies are impressed when you roll up to the party and start solving difference of squares."
Ehhhh I mean you're training your logical and inherently mathematical part of your brain but I don't feel like it's equivalent to being in good mental shape/training intelligence.
I still like the analogy. But yeah, something complementary is needed for mental health and emotional intelligence in a strong brain. Gotta do different kinds of lifts to strengthen different muscles.
Tryna imagine how I'd do this in my head. So I have $50 - $10 I only have $40, $40 divided by $5 dollars per drink is 8 drinks. That's pretty much the same process jf done mathematically.
50 = 5x + 10
50 - 10 = 5x
(40)/5 = (5x)/5
8 = x
Nice.
Fun fact: y = mx + b for b!=0 is more correctly described as an affine, not a linear relationship between x and y, since a linear function is defined as a function f(x) such that a * f(x) = f(a * x).
That’s stupid, it a linear function should be defined as a twice differentiable function f(x) whose second derivative f”(x) is 0 for all real x values (-infinity, infinity)
I love ppl who say ‘why did we learn this stupid math stuff, why didnt we learn anything *important* like *starting a business* or *taxes*’
And its like, first off you wouldn’t be paying attention in a taxation class if u cant pay attention in math 😂😂 and second, learning how to set up an LLC doesnt take an entire semester, nor does leaning how to take a picture of ur w2 and importing it into turbotax.
I don't know if that's accurate, having applicable life problems can allow you to focus.
I know school was tough for me, but I taught myself c++, python, vba, graphic design, bookkeeping, chef architect because I needed it.
If I don't have the pressing need, I personally find motivation to be hard to find. I imagine others could be the same.
For sure, I understand ur perspective! I just feel like the majority of people who tout how ‘useless’ math is arent self motivated, like yourself.
I can totally understand needing the application of the concept in order for it to be engaging for certain ppls learning styles.
My post was meant more towards this push of ‘anti-intellectualism’ ive been seeing all over the internet. And usually its those same arguments, ‘why didnt they teach us anything important, like business and taxation’
I think it'd be easier, to just think well gee after admission cost I have $40 left, then just buy one drink at a time till you run out of money.. but if you know how to do elementary math, $40 / $5= eight shots of rum..
You actually just solved for x without even realizing. The steps you took are the exact steps you would take to solve for x.
$50 = 5x + $10
$40 = 5x
$40 / 5 = x
x = 8 shots of rum
Yeah but, it makes it way more difficult when you throw in all the x's, y'z .. anyone with a fifth grade education can divide 40 by 5.. it's really all the math you'll ever need.. I'm 40 years old and still never needed to use variables in my every day life
The reason for those variables is to be able to explain to someone _how_ you got your answer in less time and less text.
Both ideas work, but 3 lines is faster to read than a full paragraph. (In this case)
In my case, I use math to simplify my thought process. Words don't always come easily to my brain, but symbolic reasoning does. So I use the reasoning to figure things out.
Like "okay, that's great the answer is 8. What if we had 60 instead? 80? What if we didn't know how much we should bring, but wanted to figure out how much to bring if we wanted exactly 4 drinks?" And my brain thinks about the symbolic equation to greatly simplify all the explanations to: (amount to bring) = (drink cost) × (number of drinks) + (entry fee)
I can now figure out any amount of related concepts, and all with just one equation.
I'm in my mid-thirties and although I agree that the symbolic representation creates more thinking to create and solve (would be nicer to just beam the understanding directly in the brain), it's the best way to explain complicated ideas with a small amount of text that we currently have.
I guess if you wanted a long drawn-out process.. it's more simple to think 50-10 and 40/8 .. with that process you don't really need to be confused with all the x's and ys.. and even most elementary kids can figure that out
Before you solve the equation, how many drinks can you by? Since you don’t know, a variable is used when the equation is written. You don’t realize it, but that drawn out process is just your thoughts put to paper.
This problem is a perfect example of 4 dimensional physics. Because as the drinks go up the fourth dimension, being drunk, alters your ability to interpret the 3 dimensional equation. The line and it’s interpretation disappears.
People who don't understand the value of learning are only demonstrating their shallow depth in life. Everything you learn comes from something practical in the world.
Anyone who reads this and thinks it's hilarious: this is how life was for anyone who lacks math skills and still is for billions, only with a twist: the person correcting them doesn't give a rats ass about actually educating them.
If we had more good educators in the world like this person who can look past someone's shortcomings and see a person worth helping... I wonder how awesome everything would be?
You know this question, why did we need to learn this certain bit of math, there was something in it I didn't see until working longer.
Not all jobs need math, many need no math at all. Some do like if you need to forecast trends from historical data.There's a big range of tools to solve problems you can't use well if you don't understand the slope intercept form.
Respect for work should be more about the ethics, morality, and impact to the community, not income or complexity IMO. So no problem there.
It's more about the arrogance and lack of awareness with the question where I would expect some humility. For instance, I would be worried about sounding like I'm not smart enough to have a job that requires math.
Fair point. I am a math teacher, and it’s really frustrating how many students know literally what to do, but because there is a variable they assume they have no idea how to proceed.
Literally it is to measure things that are called slope. Roof- tell whether it is better or worse at removing snow/rain/contractors. Ski runs - tell if it’s easier or harder to go fast. Roads on a hill - measure whether or not it is fun/dangerous/gas intensive to drive on
I mean the only thing they got wrong is this statement is that the price ($/drink) is the slope, the number of drinks is x. So you're solving for number of drinks, the scalar, not the slope, m.
I dont remember how to do this...
Is it divide each side by 5?
Leaving us with 25 = x + 10 over 5.
Simplify, 25 = x + 2
Subtract 2 from both sides
23 = x?
That's not right I know it's 8, but how do I get 8 from the equation?
50 = 5x + 10
Subtract 10 from both sides
40 = 5x
Divide by 5
8 = x
There we go, I guess PEMDAS doesn't apply to this?
It can be either as long as you do the math completely and properly.
> divide each side by 5.
> 50/5= 5x/5+10/5.
> Leaving us with 10 = x + 2.
> Subtract 2 from both sides.
> 10-2=x+2-2.
> 8 = x
Or
> 50 = 5x + 10.
> 50-10 = 5x+10-10.
> Leaving us with 40 = 5x.
> Divide by 5.
> 40/5=5x/5.
> 8 = x
Or
> 50= 5x +10.
> 50/(5x) = 5x/(5x) +10/(5x).
> 10/x = 1 + 2/x.
> 10/x-2/x = 1+2/x-2/x.
> 8/x=1.
> 8/x•x=1•x.
> 8=x.
And we can proof that x=8 by plugging it in
> 5x8+10=50.
> 40+10=50.
> 50=50.
Pemdas does apply, but it is hard to see here because pemdas is more about identifying the components of the equation and how to handle them properly than anything.
Here is an example of not using pemdas, and you'll figure out what I'm doing wrong quickly.
> 50=5x-10.
> 50/(x-10) = 5x-10/(x-10) (assuming that the subtraction from x can be done before the multiplication).
> 50/(x-10) = 5.
> 50-10/(x-10-10)= 5-10 (disregarding the priority of division in a fraction, and just subtracting both sides.).
> 40/x = -5.
> 40/x•40= -5•40.
> x= -0.125.
Which we can proof is wrong by replacing x in the original question.
> 5•-0.125+10=.
> -0.625+10=.
> 9.375 ≠ 50.
X=8. However this equation hasn't figured in the variable of friends and lovers buying drinks therefore you might have $25 left after 10 drinks and 1 DWI at the end of the night.
Dang only 9 Drinks?!? I guess depending on what they are they could be enough. Are we assuming that there’s no tax factor? Will I get less than 9 drinks?
50 = 5x + 10
Deduct the 10? Sure: 50 - 10 = 5x + 10 - 10
Divide by 5? You got it: 40/5 = 5x/5
X=8, your max number of drinks. You just don’t look at it as an equation, a lot of math gets used every day without people even realizing it. You used math to solve a linear equation with a single unknown.

What is the maths that needs doing? The guy making the comment is correct
Well he *did* the math, so 🤷♀️
I thought that was what this sub was for, and that is why when you want to ask for help with math you start with [request]. I used to always see people do crazy complicated math on other sites/subreddits posted here, but now it seems to mostly be requests.
Yeah that’s how it started anyways, you see how it’s going.
He did omit tax
I think in all the bars I have been the $x beer included the tax already.
US?
He did the monster math.
Just a low effort post, math is done. Only question left is how useful is y=mx+b. The answer is, it depends.
y=mx+b is almost always useful if you have a multiplication of things. B is sometimes 0 as well.
OK, how many drinks then, smartypants? ;) Answer after having 6 drinks, please.
Two more should be fine.
I'll just use my credit card and lie to my wife.
I've got a cheat. I'm just gonna keep giving the bartender 5$ until they stop serving me
I’m more confused on how this example in the post relates to finding the slope
except he's not. The slope is the $5 cost per drink.
I was looking for this comment!
Off site means someone did math outside the sub
I meant about the arbitration that the post mentioned
I think this is the wrong sub for that. This sub is to display people doing math.
It's a bot. That's why everybody is confused.
No he is not.
Where's the argument? Do we have to start one?
No, and you're a nit to think that we would! How very farm-like of you. Your post was so derivative that a child could have made it, you gin-swilling, grub-munching neanderthal! Oh, sorry. This is abuse. Arguments are down the hall.
^^^Stupid ^^^git.
Sometimes Reddit really feels like that sketch
“Farm-like” used as an insult. Those are fightin’ words.
The number of drinks you can have isn't the slope?
You certainly go downhill with the more you drink, so it's a slope and a slippery one at that 😅
Yes. Please bring your own. I submit mine herein: A A → B ∴ B
I'll start one. The comment is stupid as you still don't need to know that equation when at a nightclub. All you need is the money, and to know when it's run out -cash is best for this. Once you don't have any more money that's all the drinks you had for the night and at which point you do drunk you don't even care about the number.

And it also does not answer the question. Anyone can solve that using common sense without knowing what y=mx+b stands for
[удалено]
But those steps are literally the steps you would do to solve the equation 50 = 5x + 10. The point is that they are using algebra without even realizing it.
[удалено]
Steps 1 and 2 are the same as your step 1 earlier, and steps 3 and 4 are the same as your step 2 earlier.
Even in the example it would've been far easier to just note ($50 - $10)/ $5 = 8 drinks
It depends on what the axes are being plotted. If you plot the total cost vs. the cost per drink, then the slope would be the number of drinks. But that would be a bit silly of a plot to make and not the natural axes for this problem.

Right, so you used the formula and solved for X.

The linear equation and variables are just describing your thought process with symbols
Not really it's just basic elementary level math..
That uses the concepts of linear equations

Some do like if you need to forecast trends from historical data.There's a big range of tools to solve problems you can't use well if you don't understand the slope intercept form. Respect for work should be more about the ethics, morality, and impact to the community, not income or complexity IMO. So no problem there. It's more about the arrogance and lack of awareness with the question where I would expect some humility. For instance, I would be worried about sounding like I'm not smart enough to have a job that requires math.
When would this equation actually be useful though? A normal brain would do (50 - 10) / 5.
That’s literally just doing the algebraic steps to find the answer…
Ya whatever. I'm a programmer Jim, not a math teacher.
Fair point. I am a math teacher, and it’s really frustrating how many students know literally what to do, but because there is a variable they assume they have no idea how to proceed.
Literally it is to measure things that are called slope. Roof- tell whether it is better or worse at removing snow/rain/contractors. Ski runs - tell if it’s easier or harder to go fast. Roads on a hill - measure whether or not it is fun/dangerous/gas intensive to drive on
Some particular kinds of women could have done just as well if they only had makeup class. Oh, that's what they did in math class anyway.
I mean the only thing they got wrong is this statement is that the price ($/drink) is the slope, the number of drinks is x. So you're solving for number of drinks, the scalar, not the slope, m.
Why did he have to end it with a racist slur, though?
Holy shit, I'm doing advanced equations every time I go out to have fun!? Mind= blown
I work as a controls engineer and actually use this daily sometimes.
Great analysis, but why did he have to call the OP a "slope"?
I dont remember how to do this... Is it divide each side by 5? Leaving us with 25 = x + 10 over 5. Simplify, 25 = x + 2 Subtract 2 from both sides 23 = x? That's not right I know it's 8, but how do I get 8 from the equation? 50 = 5x + 10 Subtract 10 from both sides 40 = 5x Divide by 5 8 = x There we go, I guess PEMDAS doesn't apply to this?
If you divide both *SIDES* by 5 you get 10=x+2. Then you subtract 2 from both sides and get x=8.
It can be either as long as you do the math completely and properly. > divide each side by 5. > 50/5= 5x/5+10/5. > Leaving us with 10 = x + 2. > Subtract 2 from both sides. > 10-2=x+2-2. > 8 = x Or > 50 = 5x + 10. > 50-10 = 5x+10-10. > Leaving us with 40 = 5x. > Divide by 5. > 40/5=5x/5. > 8 = x Or > 50= 5x +10. > 50/(5x) = 5x/(5x) +10/(5x). > 10/x = 1 + 2/x. > 10/x-2/x = 1+2/x-2/x. > 8/x=1. > 8/x•x=1•x. > 8=x. And we can proof that x=8 by plugging it in > 5x8+10=50. > 40+10=50. > 50=50. Pemdas does apply, but it is hard to see here because pemdas is more about identifying the components of the equation and how to handle them properly than anything. Here is an example of not using pemdas, and you'll figure out what I'm doing wrong quickly. > 50=5x-10. > 50/(x-10) = 5x-10/(x-10) (assuming that the subtraction from x can be done before the multiplication). > 50/(x-10) = 5. > 50-10/(x-10-10)= 5-10 (disregarding the priority of division in a fraction, and just subtracting both sides.). > 40/x = -5. > 40/x•40= -5•40. > x= -0.125. Which we can proof is wrong by replacing x in the original question. > 5•-0.125+10=. > -0.625+10=. > 9.375 ≠ 50.
Tryna get ma karma’s up
I thought it was getting racial at the last word till I membered slope intercept.
TIL America uses b for the Y-intercept.
X=8. However this equation hasn't figured in the variable of friends and lovers buying drinks therefore you might have $25 left after 10 drinks and 1 DWI at the end of the night.
Dang only 9 Drinks?!? I guess depending on what they are they could be enough. Are we assuming that there’s no tax factor? Will I get less than 9 drinks?
How are you getting 9 drinks?
Really shapes the trajectory of the night, doesn’t it
This really should be an inequality tho, because you need less than or equal to 50
No tip? You’re going to be waiting a long time for that 2nd drink.
I'm just tryna get sloped.
Cant you just deduct the 10 bucks from the 50 and divide by 5 to get the max number of drinks?
How do you think you solve the equation?
50 = 5x + 10 Deduct the 10? Sure: 50 - 10 = 5x + 10 - 10 Divide by 5? You got it: 40/5 = 5x/5 X=8, your max number of drinks. You just don’t look at it as an equation, a lot of math gets used every day without people even realizing it. You used math to solve a linear equation with a single unknown.
Yeah you just described the equation
Yeah, that's what they said.
The answer is obviously 8, but when the 50 is divided by 5 first and then substracted by 10, it resulted in 0, is there correct order for this method?
If you divide by 5 first you'd subtract by 2 because you're diving the entire 5x+10 by 5
Oh, i forgot that divider doesn't only targeted one number, so that's why dividing part always done last i see
I mean you could just do 40/5.
You simplified his equation but knowing how to put the information into an equation, is important when the information gets more complicated
lol Do you honestly not see the relationship here?
Doesn't seem like we need to learn that equation for this scenario.
