13. while watching a football game, lin chow decided to list yardage gained as positive integers and yardage lost as negative integers. after these plays, lin recorded 14, -7, and 9. what was the net gain or loss?
Answer
Explanation:
Step1: Define the operation
We need to find the sum of the yard - age changes. Positive integers represent yard - age gain and negative integers represent yard - age loss. The numbers are 14, - 7, and 9.
Step2: Add the numbers
We add the integers together: (14+( - 7)+9). First, (14+( - 7)=14 - 7 = 7). Then, (7 + 9=16).
Answer:
16
