one equal to two ?

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.

In between your ears: obviously the answer is 42.
the answer is 42 :laugh: :laugh:

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?

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 ? -

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.

How about this... ;P 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[^] :-D Even google 0.999999999999999 = 1[^] if you're still unconvinced.

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