A power of two is a number of the form 2 n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent. Powers of two with non-negative exponents are integers: 2 0 = 1, 2 1 = 2, and 2 n is two multiplied by itself n times. The first ten powers of 2 for non-negative values of n are:
