Answer :
To find the expression, take the numbers over par as positives and the numbers under pair as negatives, so you can write this expression:
15 + (-3) + 6 + (-3) =
That is the expression.
To find the result you group the positives and group the negatives:
Positives: 15 + 6 = 21
Negatives: 3 + 3 = 6
Now subtract the total negative from the total positive
21 - 6 = 15.
So, he got 15 over par in the last four holes.
Given that he need at most 10 you know he couldn't beat his best score.
He score 15 - 10 = 5 over what he needed.
15 + (-3) + 6 + (-3) =
That is the expression.

21 - 6 = 15.
