Difference rather than subtract

[Fashoomp]

I am comparing a bunch of numbers against each other to calculate a distance. However, I do not want a negative answer. I want to know how if I enter a number, and then a second number, it will find the difference between the 2, so it doesn't matter whether I enter the bigger number first or second.

I know how to do it with just 2, but not when I'm comparing lots of numbers.
