Calculate: 12 ÷ 4 + 3 × 2

Back

9 (First, divide 12 ÷ 4 = 3, then multiply 3 × 2 = 6, and finally add 3 + 6 = 9).

Front

What operation do you perform first in the expression 8 - 2 × 3?

Back

You perform multiplication first: 2 × 3 = 6, then subtract: 8 - 6 = 2.

Calculate: 7 + (3 × 2) - 4

Back

10 (First, multiply 3 × 2 = 6, then add 7 + 6 = 13, and finally subtract 4: 13 - 4 = 9).

Front

What is the result of 9 - 3 + 2 × 5?

Back

14 (First, multiply 2 × 5 = 10, then subtract: 9 - 3 = 6, and finally add: 6 + 10 = 16).
