Negative exponents are essentially the inverse of the base elevated to the corresponding positive exponent. For instance, a^-n is the same as 1/a^n. In simpler terms, a negative exponent reveals the number of times one needs to divide 1 by the base, instead of multiplying it. The rules applied to these negative exponents are similar to those used for positive exponents.
