the Badgers played football against the Raiders. the Badgers had a gain of 7 yards on their first play and a loss of 15 yards on their second play. on the third day, there was a loss of 18 yards. Find the total gain or loss for the 3 days
I think you meant for the three plays. If I'm incorrect, leave a comment below this answer and I'll edit my answer.
Play One = + 7 yards. Play Two = - 15 yards. Play Three = -18 yards
Net = 7 - 15 - 18 = - 26 yards. That means that they are 26 yards behind where the ball started for the first play. They are not in a very good position.
