Sure it does. When you have a string of three or more factors to be multiplied, the order in which you do the multiplying makes no difference.
(2 × 3) × 5
= 2 × (3 × 5)
6 × 5
= 2 × 15 = 30.
You could arrange the factors in any order you please:
5 × 2 × 3 = 3 × 5 × 2 = 30.
Now return to Page 13 and pick the correct answer.
