how to prove 1>0

Question

prove that 1>0

Answer 1

You first need to prove that the square of a non-zero number is always positive.

Then, 1² = 1 > 0.

 

To prove that the square of a non-zero number is always positive, you start by proving that for a and b  both greater than zero (-a)(-b) = ab > 0.  If you need help with that, please send me a message.
