For example, 36 can be thought of as 32 + 4, 20 + 16, 40 – 4, 12 X 3, 22 x 32 , etc.[1] Added Note: Decomposing numbers means rewriting a number as the sum, product or difference of other numbers. Composing numbers means putting together numbers that are represented as a sum or product in order to obtain a single number.
