Solve the following:

39 ÷ (3+10) - 3 × 7 =

39 ÷ (3+10) - 3 × 7 =

`______`

.Solve the following:

39 ÷ (3+10) - 3 × 7 =

39 ÷ (3+10) - 3 × 7 =

`______`

.Detailed Explanation

Solve by using the order of operations. It’s easy to do if you remember the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).

39 ÷ (3+10) - 3 × 7

= 39 ÷ 13 - 3 × 7

= 39 ÷ 13 - 21 = 3 - 21 = -18

39 ÷ (3+10) - 3 × 7

= 39 ÷ 13 - 3 × 7

= 39 ÷ 13 - 21 = 3 - 21 = -18
