In golf, if you are over par, then your score is represented by values over zero and with a plus. Since Jewels' score was 5 over on the first hole (dang... that's a quintuple bogey (which is horrible)), she had a +5 on the first hole. But for the next 9 holes, she scored 4 under, which is represented by -4. Add 5 and -4 and you get +1. She still has 8 holes left in that round if she wants to get below par.
