In algebra, the inequality of arithmetic and geometric means, or the AM–GM inequality, states that the arithmetic mean is greater than or equal to the geometric mean of any list of nonnegative reals; furthermore, equality holds if and only if every real in the list is the same.
In symbols, the inequality states that for any ,
with equality if and only if
