Can 1=2?I need a correct proof.

Question

anonymous · Answer

No. Obviously.

The proof involves using complex numbers and the fallacy lies in the fact that square roots are defined in a certain way.

anonymous · Answer

no my teacher already proved that it wasnt true

anonymous · Answer

yes guys all are correct! Just have a look at this link http://www.math.toronto.edu/mathnet/falseProofs/first1eq2.html

anonymous · Answer

That is a matter of definition. Proof relies on definitions. It can be done in numerous ways based on what we start with. (It doesn't necessarily require any specific part such as complex numbers.)

If we start with 1 and 2 representing two different numbers, then they are.

It is a good one to do for a maths exhibition!!!

anonymous · Answer

The 1=2 is a classic fallacious proof which includes an erroneous step of dividing by zero. :)

if 1 and 2 represent quantities, then in order for them to equal they would have to correspond one to one

1 = *
2 = * *

they do not correspond one to one
