Carol and Sherry are simplifying the expression shown below.

6 + 8(5 - 3) + 2

Carol says the simplified expression is 45. Sherry says it is 24. Who is correct?

• Sherry

• Carol

• Neither

Given the following expression:

32 ÷ 4 + 4 x 11 - 5

Where should the parentheses go so that when it is simplified you get 39?

• (32 ÷ 4) + 4 x 11 - 5

• 32 ÷ (4 + 4) x 11 - 5

• 32 ÷ 4 + (4 x 11) - 5

• 32 ÷ 4 + 4 x (11 - 5)
