One can obtain an addition chain for from an addition chain for by including one additional sum = +, from which follows the inequality () + on the lengths of the chains for and . However, this is not always an equality, as in some cases 2 n {\displaystyle 2n} may have a shorter chain than the one obtained in this way.
