Measure how many units $E$ is from $B?$

How many units $A$ is from $B$ towards right?

How many units $D$ is from $E$ towards left?

How many units $D$ is from $F$ towards left?

What is the relation between the numbers which are at $A$ and $F?$

What are the absolute values of the numbers of $B$ and $E?$
