1=1
a=a <=> a/a=1
a²=a² ??
a=b <=> a/b=1
a²=b² ??
then
a=b
a-c = b-c ?
a-a = a-a (assuming a=b and a=c) ??
Where is the division by zero ? I've added c at both sides of =

At the final step, you effectively have a=0 , which means that a/a=1 on the second line is division by zero.
But why were b and c introduced? It's just nonsense.
Additionally, a²=b² certainly does not mean a=b .

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...

In between your ears: obviously the answer is 42.

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.

The error is simultaneously in line 5, your misunderstanding of basic maths, and your posting of this question.

The error is I haven't had coffee yet.

welcome to the lounge. I know this isn't quite your first post - but nearly. And I would like to apologise for the negativity your post received.
For someone who hadn't seen that 'proof' before it may have been interesting - as you can see, not only have the majority here seen it (more than once!) but they like to stuff it down your throat - whether to big-note themselves or simply in an attempt to belittle you we cannot tell.
They should be ashamed.
Merry Xmas

How about this...
Start with this:
1/9 = 1/9
Then convert one side to decimal equivalent (which is infinitely recurring)
1/9 = 0.11111111111111111111111111111111111111111111111111111111...(etc etc)
Then multiply both sides by nine
1 = 0.9999999999999999999999999999999999999999999999999999999999...(etc etc)
Therefore, 1 is equal to 0.9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999...(where the 9's are in infinite recursion).
And yes, this actually is mathematically correct.

I agree but here
1/9 = 0.111111111111111111111111......
is not really true ;
we lost 0.000000000000000000000.......9
I could write
1/9~= 0.111111111111111111111111......
then
1 ~= 0.9999999999999999999999999......
??

Wish I could agree, but I can't... read all about it[^]
Even google 0.999999999999999 = 1[^] if you're still unconvinced.

Ah là là Mathematics !!

a(a-a) = (a+a)(a-a) // divide by (a-a), i.e. divide by 0
a = a+a
Division by zero is a no-no because it can lead to "impossible" results like the above.

The value of a is irrelevant; a - a == 0, and factoring out a - a is division by 0, which is forbidden.
I am not a mathematician, so I don't know if it is possible to create a self-consistent arithmetic in which division by 0 does not result in nonsensical results. All I know is that in the arithmetic I learnt in school it is forbidden.

Sure !
number can never be divided by zero 0 ; even 0/0
It is the real error of my process
