A football team gained 9 yards on one play and then lost 22 yards on the next. Write a sum of integers to find the overall change in field position?

Gained 9 yards, then lost 22:

9-22=c

-13=c

Therefore, the football team lost 13 yards in overall change in field position. Meaning, the team didn't gain any yards, they lost 13.

Gain = +

lost = -

+9 + (-22) = 9-22 = - 13 yards
