Notice that:
2 × 5 = 10 and 5 × 2 = 10
10 × 2 = 20 and 2 × 10 = 20
5 × 10 = 50 and 10 × 5 = 50
7 × 5 = 35 and 5 × 7 = 35
Multiplying can be done in any order.
You always get the same answer.
*****WARNING*****
Dividing is different.
10 ÷ 5 = 2 but 5 ÷ 10 = ½
They are NOT the same.
Dividing cannot be done in any order.
