Front

What do you do first in the expression: 3 + 5 x 2?

Back

You do the multiplication first: 5 x 2 = 10, then add 3.

Front

Solve: 6 + 2 x 3

Back

12

Front

Solve: (4 + 2) x 3

Back

18

Front

What is the result of 10 - 2 x 5?

Back

0 (You do multiplication first: 2 x 5 = 10, then 10 - 10 = 0).

Front

What should you do first in the expression: 12 ÷ 4 x 3?

Back

You do the division first: 12 ÷ 4 = 3, then multiply by 3.

Front

Solve: 8 ÷ 2 + 3 x 4

Back

14

Front

What is the result of 5 + 3 x (2 + 1)?

Back

14 (You solve inside the parentheses first: 2 + 1 = 3, then 3 x 3 = 9, and finally 5 + 9 = 14).

Front

What is the first step in solving: 15 - 3 x 2?

Back

You do the multiplication first: 3 x 2 = 6, then subtract from 15.
