The __________________ prоperty оf multiplicаtiоn stаtes thаt the order in which numbers are multiplied does not change the final result. This means that parentheses can be used to group numbers in different ways, and the product will be the same. For example, the following expressions all have the same final result: 2 × 4 × 5 = 8 × 5 = 40, (2 × 4) × 5 = 8 × 5 = 40, and 2 × (4 × 5) = 2 × 20 = 40.
