Simplify: -5^3 -3

-125 -3 = 122 correct?

  • Math 115 24 -

    No, on two counts
    -125 + 3 = -122
    -125 - 3 = -128

  • Math 115 24 -

    -5 * -5 = 25
    25 * -5 = -125

    -125 -3 = -128

    Look at what you are doing on a number line, negative is left. More negative is more left.

    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.

    i think -125-3=-128
