**Absolute Value**

The **absolute value** of a number is just the number itself excluding its sign.

For example, the absolute value of -2, written as \left| -2 \right| , is equal to 2. Also, the absolute value of +7, written as \left| +7 \right| , is just 7.

The absolute value of a number can also be interpreted as the distance of a point from zero on the number line. Since distance cannot be negative, that’s the reason why the absolute value of a number is always positive.
