**Absolute
Value **

**When we want to talk about how “large” a number is without regard as to whether it is positive or negative, we use the**

*absolute value*function. The absolute value of a number is the distance from that number to the origin (zero) on the number line. That distance is always given as a non-negative number.**In short:**

**If a number is positive (or zero), the absolute value function does nothing to it:**_{}**If a number is negative, the absolute value function makes it positive:**_{}

**WARNING:**

**If there is arithmetic to do inside the absolute value sign, you must do it before taking the absolute value—the absolute value function acts on the**

**result of whatever is inside it. For example, a common error is**

_{}**(WRONG)**

**The correct result is**

_{}
