Question 28164: Earlier I asked why any number that has "zero" as the exponent equals 1. It was answered by saying that the answer will always be 1. But my question is WHY is the answer always one.

If it is to the zero power, then it should be multiplied zero times, but the answer is "1". WHY is this?
