Find the distance between the following numbers on the real number line

We have to find the distance between a = -10 and b = -3 in the number line.
We can graph them as:
The distance is 7 units.
It can also be calculated as:
[tex]d=|a-b|=|-10-(-3)|=|-10+3|=|-7|=7[/tex]Answer: the distance is 7 units.
