Is this supposed to be the same as 9-(-9)?
anonymous
  • anonymous
nope
anonymous
  • anonymous
modulus and brackets are different
anonymous
  • anonymous
a modulus takes the positive number inside the |..| so |-1|=1,... |-n|=n
anonymous
  • anonymous
so what would |-9| equal?
anonymous
  • anonymous
9
anonymous
  • anonymous
correct!
anonymous
  • anonymous
Is that it?
anonymous
  • anonymous
nope, so we know |-9|=9 right?
anonymous
  • anonymous
so what is 9-|-9|
anonymous
  • anonymous
Yes
anonymous
  • anonymous
9-|-9|=9-9
anonymous
  • anonymous
What do I do now?
anonymous
  • anonymous
evaluate 9-9
anonymous
  • anonymous
what is that?
anonymous
  • anonymous
0 right?
anonymous
  • anonymous
Would 9-9 be 18?
anonymous
  • anonymous
how did you get that...
anonymous
  • anonymous
all we are doing is subtracting 9 from 9
anonymous
  • anonymous
I tried to follow the rules of intergers.
anonymous
  • anonymous
Then that equals 0.
anonymous
  • anonymous
correct
anonymous
  • anonymous
Is that the answer to the whole problem?
anonymous
  • anonymous
sure is
anonymous
  • anonymous
9-|-9|=0
anonymous
