This document outlines several algebraic identities involving sums and differences of terms including: the product of a sum and number, the product and squares of sums and differences, the product of a sum and difference, the sum and difference of a sum and difference, and the cubes of sums and differences. It provides the expansions of expressions like (a+b)c, (a+b)2, (a-b)2, and (a+b)3.
