Write as a sum

Theory

Write as a sum

A number or expression can be written as a sum of two or more terms. For example, the number 66 can be written as 3+33+3 or 1+2+3,1+2+3, and 10x10x can be written as 4x+6x.4x+6x. The variations are infinite but the aim is usually to make a simplification easier, e.g. factoring.
