Hi Dalinda,
I don't play golf either, but let's try to figure this out.
Let's make par equal to zero and strokes more than par, positive and strokes less than par, negative. In golf, the lower your score, the better so negative numbers are good.
So let's assign values to Frank's scores:
par = 0
2 birdies = 2 (-1) = -2
eagle = -2
4 bogies = 4(1) = +4
double bogie = +2
0 - 2 - 2 + 4 + 2 = +2 which is 2 points above par.
