    what is the modulus of a negative number?

    we simply take the positive value inside the modulus...

    Is this supposed to be the same as 9-(-9)?

    a modulus takes the positive number inside the |..| so |-1|=1,... |-n|=n

    so what would |-9| equal?

    nope, so we know |-9|=9 right?

    all we are doing is subtracting 9 from 9

    I tried to follow the rules of intergers.

  24. anonymous

    Then that equals 0.
