Adding can be thought of as going right on the number line.
0
Practice makes perfect
Let's perform the addition.
- 2+2
Below we will demonstrate how to do it using a number line. First, we draw an arrow from 0 to - 2 to represent - 2. Then we draw an arrow 2 units to the right to represent adding 2. Note that the length of each arrow is the absolute value of the number it represents.
The resulting position, after moving to the right on the number line, is the sum.
- 2+ 2=0
