#1**+2 **

The absolute value of a number is its "distance" from zero. Imagine a number line...notice that -5 and 5 are both equally "far away" from zero. They are both 5 units away from zero.

| -5 | = | 5 |

5 = 5

So...to take the absolute value of a negative number, drop the negative sign.

And to take the absolute value of a positive number, leave it alone.
