Simplify: -5^3 -3

-125 -3 = 122 correct?
Answered by Damon
No, on two counts
-125 + 3 = -122
-125 - 3 = -128
Answered by Ms. Sue
-5 * -5 = 25
25 * -5 = -125

-125 -3 = -128
Answered by Damon
Look at what you are doing on a number line, negative is left. More negative is more left.
Answered by Damon
Oh, I bet I know what caused the confusion:
If you multiply or divide two negative numbers you change the sign to positive.
HOWEVER
That does not happen when adding.
