Front

In the expression 6 x 7 + (9 - 3) + 2, what should you calculate first?

Back

You should calculate (9 - 3) first.

Front

What is the solution to 3(2)?

Back

6

Front

What is the value of 8 + 2 x 5?

Back

18 (because you do the multiplication first: 2 x 5 = 10, then add 8).

Front

If you have the expression 4 + 3 x 2 - 1, what is the first step?

Back

The first step is to perform the multiplication: 3 x 2 = 6.

Front

What is the result of 10 - 2 + 3?

Back

11 (because you perform addition and subtraction from left to right).
