Question

Julio's football team gained 5 yards from their starting

position on their first play. On the second play, his
team lost 12 yards. On the third play, the team gained
9 yards.
Is the team back to their starting point?
Explain your answer.

Answer 1

No

Reason:

For example if the starting point is 1 and they gained 5 they would be at 6.

Next, if they lost 12 they would be at -6.

Then if they gained 9 they would be at 3.

Since their starting point was 1 they wouldn't be where they started.

(Sorry if this is wrong I don't know about football, using the mathematical approach)
