Front

What operation should be performed first in the expression: 8 + 2 × 5?

Back

Multiplication (2 × 5 = 10, then 8 + 10 = 18).

Front

In the expression 3 + (4 × 2), which operation is performed first?

Back

The operation inside the parentheses (4 × 2 = 8).

Front

What is the result of 6 ÷ 2 × 3?

Back

9 (First, 6 ÷ 2 = 3, then 3 × 3 = 9).

Front

What is the value of 5 + 3 × 2 - 4?

Back

7 (First, 3 × 2 = 6, then 5 + 6 - 4 = 7).

Front

What is the result of 10 - 4 ÷ 1 × 5?

Back

8 (First, 4 ÷ 1 = 4, then 10 - 4 × 5 = 10 - 20 = -10).

Front

In the expression 7 - (2 + 3) ÷ 5, what operation is done first?

Back

Addition inside the parentheses (2 + 3 = 5).

Front

What is the value of 40 - 2^4 + 8?

Back

32 (First, 2^4 = 16, then 40 - 16 + 8 = 32).

Front

What is the result of 91 + 27 ÷ (72 ÷ 24)?

Back

100 (First, 72 ÷ 24 = 3, then 27 ÷ 3 = 9, and finally 91 + 9 = 100).
