For the future, please do not use capital letters/upper case as they are much more difficult to read and in computer language they are considered as rude as shouting.

I am very sorry about that.
I am stuck on:
a football team gained 5 yards on one play, then lost 10 yards the next play. On the thrid play it gained 2 yards . How many yards did the team ove in those 3 plays?
5 - (-10) + 2
Answered by Ms. Sue
Almost right.

5 - 10 + 2 = - 3 yards

Think about it this way.

Suppose the team started on the 20-yard line.

It gained 5 yards so it was on the 25-yard-line.

It lost 10 yards taking it to the 15-yard-line.

It then gained 2 yards, so it was on 17-yard-line.

20 - 17 = a loss of 3 yards.
