Answer:
Step-by-step explanation: so if they gain 3 yards on the first play it’s +3, however, if they lose 6 yards it pushes them back 3 yards which offsets it to 0, then you have an additional 3 to add to the back setting putting the team at -3 yards. Finally, the last play is 8 yards. If you take the -3 and add it to the 8 it puts you at 0, and then you have 5 left over which puts you a gaining of 5 total for the overall.
