**Problem**:

Of the five coordinates associated with points A, B, C, D, and E on the number line above, which has the greatest absolute value?

**Solution**:

The absolute value is greatest for the point farthest from the origin (0), which is point A.

**Strategy**:

Absolute value is the distance away from the orgin. Because you can never have a negative distance, the absolute value is always positive. For this problem, choose the coordinate that has the greatest distance from the orgin.
