$\"\"$

$\"\"$ represents the distance between some unknown value of the variable $\"\"$ and a point $\"\"$ on the number line.

The solution set of the inequality is the set of all numbers such that the distance from the numbers to $\"\"$ is less than $\"\"$ .

By using a number line, we can find the numbers that are $\"\"$ from $\"\"$ in either direction.
