Absolute Value
Absolute value is the non-negative value of a number, whether that number is positive or negative. You can think of a number's absolute value as its distance from zero. It can be defined as,
The absolute value of a quantity x is denoted by |x| (the quantity is enclosed between two vertical bars). Here you can see that in the graph of y = |x|, if -2 is input in to the function, 2 is the result. This is because -2 has a distance of 2 from zero. The absolute value of a number can never be negative.
Examples
-
Simplify |-5|
|-5| = 5
-
Simplify |0(5)|
|0(5)| = |0| = 0
-
Simplify -|-1|
-|-1| = -(1) = -1
-
Simplify |-5(-3) + 1|
|-5(-3) + 1| = |15 + 1| = |16| = 16
-
Simplify |8|
|8| = 8
-
Simplify |(-5)^3| |-125| = 125
