Instead of adding 3 + 3 + 3 + 3 = 12, you usually write 3 x 4 = 12. You say that you have

The simplest way to avoid mistakes in multiplication is to form the habit of checking. To check

multiplication, you use the principle that the order in which the numbers are multiplied does not affect

the product. For example, 6 x 9 = 9 x 6. You can see that the answer is the same if you multiply 16 x

18 or 18 x 16.
