Doss [256]

X^2 = x * x

Squaring something is just multiplying it by its self.

A negative times a negative = a positive

A positive times a positive = a positive

A negative times a positive = a negative

A positive times a negative = a negative

- * - = +

+ * + = +

- * + = -

+ * - = -

Here is how my 6th grade teacher helped me to remember it:

If something bad (-) happens to a bad guy (-), that is good.

If something good (+) happens to a good guy (+), that is good.

If something good (+) happens to a bad guy (-), that is bad.

I hope I helped!
