Question

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?

Answer 1

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.

Answer 2

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