Try something like this:

=ABS(H2-B2)

Or...maybe
=MAX(H2-B2)-MIN(H2-B2)

Does that help?

I am subtracting the actual daily high from the predicted daily high

My formula is this:
=H2-B2

However, I want my results to always be positive numbers. I feel like there
should be a simple mathematical answer, but I didn't pay attention very well
at school.

Thanks.
