I can use the mathematical structures that underpin multiplication and division of positive integers.

Partitioning - Partitioning is the act of splitting an object or value down into smaller parts.
Dividend - The dividend is what we are dividing.
Divisor - The divisor is what we are dividing by.
20 × 50 = 100, they partition the 2 and 5 to give 10 but count the zero as one of the 2 zeroes.
Make sure that partitions are written out fully. E.g. 20 × 50 = 2 × 5 × 10 × 10 = 10 × 100 = 1000
