NEED TO WRITE AN EXPRESSION AND SOLVE
AN AIRPLANE LEFT CHGO WHRE THE TEMP WAS 42 FAREHEIGHT . WHEN IT LANDED ANCHORAGE THE TEMP WAS 60 DEGREE LOWER
WHAT WAS THE TEMPERATURE IN ANCHORAGE?
60 - 42 =
WOULD IT BE 42 + (-60) = -18
Right.
42 + (-60) = -18
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
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.
have one more question:
-7 - (-5) -3
