Calculate: 5 + 3 x 2

Back

11 (First, multiply 3 x 2 = 6, then add 5 + 6 = 11).

Front

Calculate: (4 + 2) x 3

Back

18 (First, add 4 + 2 = 6, then multiply 6 x 3 = 18).

Which operation do you perform first in the expression 8 - 3 + 2?

Back

Subtraction (Perform 8 - 3 first, then add 2).

Front

What is the result of 10 ÷ 2 x 5?

Back

25 (Perform division first: 10 ÷ 2 = 5, then multiply: 5 x 5 = 25).

What is 3^2?

Back

9 (3 raised to the power of 2 means 3 x 3 = 9).

Front

Calculate: 12 - 4 x 2 + 1

Back

5 (First, multiply 4 x 2 = 8, then do 12 - 8 + 1 = 5).
