Why is it that when I square a negative number that I get a negitive one? (-12^2 = -144) Wouldn't that make it a negative times a negative which would equal a positive?

Order of operations. When a calculator sees -122, it sees it as 12* -1 due to order of operations. So it calculates the 122 first and then multiplys it by -1. In order to get the correct answer which is 144, you must use parenthesises and put the -12 inside so it looks like this:(-122). Hope this helped.

If you need to square negative twelve , you have to do it like this:  (-12)^2 = 144   (must use parentheses....)
