Theory

Write as a sum

A number or expression can be written as a sum of two or more terms. For example, the number

6

can be written as

3 + 3

1 + 2 + 3,

and

10 x

can be written as

4 x + 6 x .

The variations are infinite but the aim is usually to make a simplification easier, e.g. factoring.
