Question

Insert parentheses to make the following sentence true. 4 • 5 + 16 - 2 = 82

Answer 1

`4 \cdot(5 + 16) - 2 = 82`

Explanation:

The given equation is

`4 \cdot5 + 16 - 2 = 82`

We want to insert parenthesis, so that this equation will be true.

We insert parenthesis to obtain:

`4 \cdot(5 + 16) - 2`

We now use PEDMAS to simplify.

`4 \cdot(21) - 2 =82`

`84 - 2 = 82`

`82 = 82`
