Cameron is playing 9 holes of golf. he needs a total of at most 15 over par on the last four holes to beat his best golf score. on the last four holes, he scores 5 over par, 1 under par, 6 over par, and 1 under par.

Cameron is successful at beating his record since he only shot 9 over par on the last 4 holes.

To find this, first turn each score into a number. Over pars are positive and under pars are negative. This gives us the following expression.

+5 - 1 + 6 - 1 = + 9

Therefore, he stayed below the + 15 that he needed.
