|x|
x if x>=0-x if x<0
The expression |x| represents the absolute value of the number x. The absolute value is the distance between x and zero on the number line, and it is always a positive number or zero.
If x is positive or zero, then the absolute value of x is equal to x. For example, |3| = 3 and |0| = 0.
If x is negative, then the absolute value of x is equal to the opposite of x. For example, |-5| = 5 and |-2.7| = 2.7.
Therefore, we can say that |x| = x if x is greater than or equal to zero, and |x| = -x if x is less than zero.
