Front

What is the result of 8 + 2 x 5?

Back

18 (because multiplication comes before addition).

Front

What is the result of (3 + 5) x 2?

Back

16 (because you solve the parentheses first).

If you have the expression 10 - 2 x 3, what do you do first?

Back

You perform the multiplication first, so 2 x 3 = 6, then 10 - 6 = 4.
