You didn't account for 'no' being equal to -1, which would have meant you couldn't divide through by it.
And to be honest, if I had to give the word 'no' a mathematical value in the context it's used here, it would be -1.

The point is that it's amusing, even though it may technically be incorrect. Like the "proof" that 1=2. Or that all horses are the same color... iss interesting, no?

Here's an easier one:
Start with 2=1
Subtract 1.5 from both sides: .5=-.5
Square both sides: (.5)^{2}=(-.5)^{2}
Result: .25=.25
Works with any two numbers, just take the average of the two numbrrs and subtract from both sides.

It's just rewriting it to equal the same thing. Either the fail or the study would be distributed to the no and the 1, so it comes to be no study+ study. The same would go for fail. Get it?

No Study + Study = Fail + No Fail
No Study - No Fail = Fail - Study
No (Study - Fail) = -1(Study - Fail)
No = -1
No + 1 = 0
And in the last two steps, dividing by (No + 1) is dividing by 0, which you can't do.

So if you have no apples, it means you owe someone an apple?

That wasn't the context it was used here.

It's a math problem, so yes, it was. But I'll take it back if you can name me a context when "no" means -1 rather than 0.

No Study = Fail

Study = No Fail

Study - Study = Fail - Fail

0 = 0 or Study = Study or Fail = Fail, all useless.

So it's nonsense.

Of course it's nonsense. It's not meant to be taken seriously.

Yeah but if the math's wrong then what's the point? Here's one that actually works.

Money = Root (Evil)

Time = Money

Girls = Time x Money

Girls = Evil

But, that one doesn't actually work, because the equations are arbitrary.

The point is that it's amusing, even though it may technically be incorrect. Like the "proof" that 1=2. Or that all horses are the same color... iss interesting, no?

proof that 1=2?

Let a and b be equal positive real numbers.

1. a=b

2. a

^{2}=ab3. a

^{2}-b^{2}=ab-b^{2}4. (a-b)(a+b)=b(a-b) <--factored from previous step

5. a+b=b <--canceled a-b

6. b+b=b <--since a=b

7. 2b=b

8. 2=1

Sure it's incorrect, but finding out what's wrong with it is part of the fun. :D

Here's an easier one:

Start with 2=1

Subtract 1.5 from both sides: .5=-.5

Square both sides: (.5)

^{2}=(-.5)^{2}Result: .25=.25

huh. I haven't seen that one before. I like it.

Thanks, my 7th grade math teacher showed us that when trying to explain why you shouldn't set things equal to each other in a proof.

Nice, but frankly I was more intrigued by the fact that -.5 looks like Patrick Moore.

strictly speaking it should be:

(.5)

^{2}=(-.5)^{2}±0.25 = ±0.25

You might as well say 1+1= 3 so 1≠1

Umm all you've done is proven that A and B are 0?

No, that would contradict the original assumption that a and b are positive. The problem's somewhere else.

This is killing me man XD

If a=b then you can't cancel a-b because a-b=0, which you can't divide by.

I know, right? Therein lies the fun. :P

Where no+1 come from?

You'd understand if you were good at maths.

He took study common from no study and study.

It's just rewriting it to equal the same thing. Either the fail or the study would be distributed to the no and the 1, so it comes to be no study+ study. The same would go for fail. Get it?

Yeah. I just take out the common factor and put it in front, not behind, so that threw me off.

Before someone calls foul, I know this is not original. I just can't remember where I first saw it so I didn't know how to give credit.

No Study + Study = Fail + No Fail

No Study - No Fail = Fail - Study

No (Study - Fail) = -1(Study - Fail)

No = -1

No + 1 = 0

And in the last two steps, dividing by (No + 1) is dividing by 0, which you can't do.

Fail
