Asked by brian

can someone explain how to solve just not answer:

IxI if x = 12 the I are a bar?
Answered by Steve
as always,

|x| = x if x >= 0
|x| = -x if x < 0

so, is 12 positive or negative?
Answered by brian
im sorry the question is Write an integer for each expression:

[x} if x = -12
Answered by brian
does the bar around the x have anything to do with the problem.
Answered by Steve
YES! It means "absolute value". Did you not read what I wrote? That's the definition of absolute value.

|10| = 10
|-3| = 3

|-12| = 12
