Question

A set of parentheses is missing from the expression
below.
15 – 5 + 7 · 2 + 4
Which of the following expressions has the
parentheses in the correct place for the expression
to equal 52?

anonymous · Answer

Put the parentheses around the 2 + 4. 

So you would have this: 15-5 + 7 (2+4)

Since you start with parentheses first you have 2+ 4 = 6
Next you multiply. So 7 times 6  is 42
Then working from left to right, you subtract 5 from 15 and get 10
Then add 10 to 42 to get 52.
