Math problems and finding distance on a number line

Distance on a number line

• Distance is always positive so we have to use absolute values to answer

• To find distance we subtract one point from the other

• Once completed you will change your answer to a positive

Absolute Values

 $\left|\ \ \ \ \ \right|$  In case you don't remember absolute value symbols look like lines around a math problem. The also represent the distance from 0 in math, in other words they change the solution to a positive.

2 key parts to finding distance is to always subtract one point from the other and your answer should always be positive.
