Math gone wrongRelated content

Can really tell who likes math and who doesn't. The people who tell you you are wrong versus the people overwhelmed by stuff they don't understand. (P.S. You are wrong.) (A-B=A-B does not equal A+B=B), just one of many mistakes.

of course it all makes sense! boy do i have a speech with my 3rd grade teacher...

i might sound nerdy but if A=B then dividing by A-B equals dividing by zero. that's where the mistake comes.
👍: 0 ⏩: 0
Well first, as several others said, if A=B then A-B=0, and you can't divide by zero, but also, (AB-B^2)/(A-B) is B^2, not B. (I think.)

Let me think on this.
any real number you put in for A and B results in a zero divided by zero problem.
in simple terms,
0÷0 is the math equivalent of
"Screw You."

As I'm sure others have mentioned, you were right up until step 4. After that step, you miscalculated which then got you a wrong answer . . . yeah, you're probably annoyed to see this and will probably not even read it after seeing it comes from this stamp, but I did enjoy the concept behind it.

..no, it's right.
The simplification of of (A²-B²)/(A-B) is A+B (AB-B^2)/(A-B) is B.
Check Wolfram|Alpha, a computational knowledge engine if you have doubts.

But isn't it that when you divide (AB-B^2)/(A-B) you're supposed to get (B+B)? There are 3 Bs in that part of the equation and only one was divided out.
👍: 0 ⏩: 0
I f A=B
A-B = 0
So you can't divide by "A-B"
and you can't prove it mathematically

UM....I DON,T GET IT? I MEAN...WHAT ARE YOU TRYING TO PROVE HERE?
👍: 0 ⏩: 0
This is wrong since the first step!
A=B
A^2=A+B
That's just wrong..
👍: 0 ⏩: 0
If A=B then A-B = 0. You can't divide by zero. Your proof is wrong!
👍: 0 ⏩: 0
looks like my math tests, i still can't understand why am i in engineering
👍: 0 ⏩: 0
only thing is A squared doesn't equal A+B, It equals A+A buddy, check your math
👍: 0 ⏩: 1
It doesn't say that A squared would equal A+B. It says that A squared equals AxB. Also, no, A squared doesn't equal A+A (Except if A=0 or if A=2).
((Why am I commenting on this? This is like three and a half years old!))

i use this so much to make people feel like idiots its awesome.
👍: 0 ⏩: 0
plus...you went from A-B = A-B to A+B = B which it doesn't it could equal a lot of other things, but not B
👍: 0 ⏩: 0
But it's so cool. I want to show this to my Algebra Prof.
👍: 0 ⏩: 0
YES! SOMEONE ELSE NOTICED THE ERROR IN THIS PROOF! I have so much trouble explaining this to people!
👍: 0 ⏩: 0
well, you said A=B, so A-B=0... So it's your proof which is wrong, not maths 
👍: 0 ⏩: 2
I agree i just did this trick on my friend yesterday lol....he didn't get it

Shut you the fck up, cuz what Il said is right. I mean, seriously, tell someone to stfu cuz one said you cant divide by zero? I can punch you in the face when you realise the Sun is hot?
Anw, you don't have to divide by zero, cuz you have a^2-b^2 which is also (a-b)^2, which is also (a-b)(a-b), so a^2-b^2/a-b is a-b. On the other side you have ab-b^2, which is b(a-b), and b(a-b)/(a-b) is b. Anyways, that + is wrong, on the 5th line, it should be a -
So it should be
A=B
A^2=AB
A^2-B^2=AB-B^2
((A-B)^2)/(A-B)= (AB-B^2)/(A-B)
A-B=B
A=2B
B=2B
1=2
The conclusion was the right, but that signals wrong. I feel bad for posting this at dA but I just had to.

a^2-b^2 is not = with (a-b)^2 and is not = with (a-b)(a-b).
Because a^2-b^2 
(a-b)^2 =a^2-2ab+b^2. Same here, a mathematical formula.
So, you're wrong.
👍: 0 ⏩: 0
No, the plus works too, (-B^2)-(-B)=B, since a negative divided by a negative is a positive, but (AB-B^2)/(A-B) is B^2, not B, which I believe makes this false, unless I'm wrong. Also, there's the dividing by zero issue.
👍: 0 ⏩: 0
since when is a²-b² = (a-b)² ?
(a-b)² = a²-2ab-b² !
(a+b)(a-b) = a²+ab-ab-b²=a²-b² !
Also, people, dividing by zero is IMPOSSIBLE. Or equals infinity, but that's another matter.
👍: 0 ⏩: 1
Dividing by zero is possible, there's just a...
...very special way...
...to do it.

i get in this arguement with mydad
he somehow doesnt understand what devision is
you take the one number, and you cut it into as many portions as the other number
when there is zero
you are not cutting it into any portions
because the portion does not exsist, you are asking literally to cut it up exactly no times
👍: 0 ⏩: 1
Well the problem is division is not the amount of times you are supposed to cut it, but the amount or portions left. What you described there was division by 1. Division by 0 is VERY difficult to handle.

@air-vamp's English seems to be better than yours. Notice the appropriate usage of capital letters and punctuation.
Anyways, you seem to really suck at flaming. (Although, you didn't put too much effort into it, so I suppose your flame:effort ratio is pretty high. Which is not necessarily a good thing...)
