(62 – 12) × 11

• The sum of 62 and 12 times 11

• 12 minus 62 plus 11

• 62 times the difference between 12 and 11

• Eleven times the difference between 62 and 12

• 29

• 27

• 45

• 20

Answer explanation

Using the order of operations, first calculate the expression inside the parentheses: 4 + 5 = 9. Then, multiply 3 by 9 to get 27. Finally, add 2 to 27 to get the final result of 27.

• 16

• 10

• 13

• 8

Answer explanation

Substitute a=3 into the expression: 2(3+5) = 2(8) = 16. Therefore, the value of the expression is 16.
