Question

Two numbers have a sum of zero and have a distance of 2.5 units between them on the number line, what are they?

Answer 1

-1.25, 1.25

Explanation:

These two numbers, when added together, add to 0. Their difference is also 2.5:

`| - 1.25 - 1.25| = 2.5`

I found these numbers by diving the distance by two and using the positive and negative values.
