Because of the commutative property of multiplication, it is true that f x 4 = 4 x ¾. However, these expressions can be calculated in different ways even though the solutions will be the same.
Below, show two different ways of solving this problem.
First, show how 3 × 4 can be solved using repeated addition.
3 × 4 can be solved using repeated addition as follows:
3 + 3 + 3 + 3 = 12
Next, show how 4 × ¾ can be solved using division.
