How does that work?

A classic example of how one can easily be misled by mathematics when one doesn’t have efficient knowledge to know better.
2a = a, does in fact not mean that 2 = 1, but rather that a has a value that would satisfy 2a = a. Therefore a = 0 is the only possibility.

  1. Hey Lindie!!
    I did not know you knew this.
    I just want to add another thing, In line 1 u made the assumption, a=b... thus a-b=0.

    In line three or four, you divided with a-b..... thus there is an division by zero.... Oopsie!!!!

  2. I really did not see that. Just shows how easily mathematics can confuse...
