Hey do you want to lend me $2000? If so just give us half of it now, that will mean I owe you $1000 and you owe me $1000 and that will mean we are even.

Let read this :
1=1 a=a a²=a² a²-a²=a²-a² a(a-a)=(a+a)(a-a) a=a+a a(1)=a(1+1) 1=1+1 1=2Where is the error ?The error begins from first assumptions -- saying
1=1at the beginning is meaningless; everthing following can provide no additional insight.a²-a²anda-aare always zero, but this is due to the nonsense above that -- in particular, whilea²-a²=a²-a²may be true, it doesn't follow froma²=a². The idiot of a Discrete Math teacher I had in college tried showing this to the class once. :sigh: -
Nah, she didn't day "damn", she said "f......". :-D

:thumbsdown: I don't think, this is a simple factorization
That you do not think so it will not change the fact that, when you move from this line to the next, you actually divide by zero - (a-a)!!! More! A solution of an equation must be traversal to both direction - yours is not! a=a a²=a² This is a one-way step and is forbidden...

ok !! :thumbsup: My best answer[^]

:laugh: As I know mathematics doesn't approve 0=0 so, the error is a²-a²=a²-a² (meaning 0=0) exactly it is a teacher who showed it to us.
It has nothing to do with 0 equal to 0 or not (which is a mathematical game only), but the fact that division by zero is not permitted (or more precisely the outcome is undefined)...

At the final step, you effectively have
a=0, which means thata/a=1on the second line is division by zero. But why werebandcintroduced? It's just nonsense. Additionally,a²=b²certainly does not meana=b. -

a - a = 0
You cannot get anything useful from a multiplication once it has involved a zero term.
5 x 0 = 12012 x 0
does not mean that
5 = 12012
There are two kinds of people in the world: those who can extrapolate from incomplete data.

a=0 never means a/a=0 (a can never be 0). a=a <=> a/a=a/a <=> 1=1 I could fix the post as : Given a C ]--;0[ U ]0;++[ (meaning 0 excluded)
Which means that you have an equation system and not a single equation...It's a different thing to solve...

Yes, but the damage is done before that.
You mean, when OP went to learn math?
