Question

What is the distance from -4.3 to +2.1 on a number line?

Answer 1

The `-4.3` will be to the left of the `0`, and the `+2.1` to the right.

Explanation:

So we have to add up their absolute distances:
`4.3+2.1=6.4`

More algebraically correct we would subtract one value from the other and take the absolute value:
`2.1-(-4.3)=6.4`
