Hey,
I just wanted to know if someone could explain to me why the following is true:
(x+y)^2 =/= x^2 + y^2
So, in words, why doesn't the some of two numbers added together and then squared equal the sum of the numbers squared individually and then added together?
I obviously know how to show they are not equal by simply explanding the left side, but I'm looking for a really fundamental answer (i.e. is there some axiom which accounts for this?).
Thanks
