On a number line, "units" refer to the equal intervals or segments that represent values. Each unit typically corresponds to a specific numerical value, such as 1, 2, or 0.5, depending on the scale of the line. Units help in visually comparing and locating numbers accurately along the line. For example, if each unit represents 1, then the distance between 0 and 1 spans one unit.
-11 is 11 units away from zero on a number line.

The distance the number is from zero. For example, + 19 is 19 units of length on the positive side of the number line , to the right of the zero position. - 19 is 19 units of length going the other way, to the left of the zero position on a number line.
the number 2 is two units to the right of 0 on the number line. the number -2 is two units to the left of 0

A number line can help you visualize this. See http://en.wikipedia.org/wiki/Number_line for an example, and a description. On a number line, adding 3 means to go 3 units to the right; if you start at -9 and go 3 units to the right, you end at -6, 'tis as simple as that. (Subtracing a number means going a certain number of units to the left.)
