In a series of plays a football team gains 20 yards, gains 15 yards, and then lose 7 yards. What is the total gain or loss in yardage?
This is wrong
20 + 15 - 7 = ?
To find the total gain or loss in yardage, we need to add up the gains and subtract the loss.
First, let's add the gains:
20 yards + 15 yards = 35 yards
Next, let's subtract the loss:
35 yards - 7 yards = 28 yards
Therefore, the total gain or loss in yardage is 28 yards.
