    In one of the tutorials the answer stated -1 to the 0 power is +1. I don't understand why. If you have a -1 and you times it by itself 0 times, wouldn't that leave you with -1?

      So this is a trick of conventional logic vs mathematical rules. Don't confuse the absolute value of the event with whether or not the event happened. I'll explain.

      -1 times itself 0 times means that -1 was in fact multiplied by itself, the event happened, but to an exponent with an absolute value of 0. Therefore the absolute value of -1 is not affected, it remains 1, but the event still happened, so the signs also have to be multiplied, and a -x- is a +, hence the absolute value remains unchanged but the sign changes.

      I hope this makes sense, it is a difficult concept to explain.

      There doesn't need to be. If it is asking you to solve 1 to the 2nd power, you won't type 1x1, you'll type 1, because 1x1 is equal to 1. If it is asking you what 2 to the 2nd power is, type 4, not 2x2.
