Zero to the power of zero Zero to the power of zero Zero to the power of zero, denoted by 0, is a mathematical expression with no agreed-upon value. The most common possibilities are 1 or leaving the expression undefined, with justifications existing for each, depending on context. In algebra, combinatorics, or set theory, the generally agreed upon value is 0 = 1, whereas in mathematical analysis, the expression is generally left undefined. Computer programs also have differing ways of handling this expression. There are many widely used formulas having terms involving natural-number exponents that require 0 to be evaluated to 1. For example, regarding "b"
