Question

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

Answer 1

Answer:

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

Step-by-step 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.

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

$84 - 2 = 82$

$82 = 82$
