(-)+(-)=- and (+)+(-)=You need to subtract and take the sign of the bigger number

(-)-(-)=(-)+(+)

Answer 7

always add numbers...

subtracting is just "adding a negative"

5-2 is the same as:

5 + (-2) = 3

Also, one point is this:

If you have a problem like: 7-(-3); just take the 2 negatives and make a (+) out of them:

7 -(-3) = 7 -- 3 = 7+3 = 10

If that helps any

Answer 8

The sign in the parenthesis just symbolizes what kind of number we have whether it is positve or negative
