Answer:

Circle the 6.

Explanation:

In the first line, it states: 40 - 2 × 3² + 10.

Remember to follow PEMDAS. PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

In this case, instead of applying the power (3² = 3 * 3 = 9), the person simply multiplied (3² ≠ 3 * 2 = 6).

Instead, the order should look like:

40 -2 * 3² + 10

40 -2 * (3 * 3) + 10

40 -2 * (9) + 10

40 + (-2 * 9) + 10

40 + (-18) + 10

50 - 18

32
