A = Maximum(A-B, A-C, C-B)

I am not sure where to post this question, but I found this site through a google search. I ran across an equation used in trading futures:

True Range = Maximum(H-L, H-PDC, PDC-L)

H = Current High
L = Current Low
PDC = Previous Day's Close

What I am not sure of, does this question mean that True Range is the maximum of either H-L, H-PDC, or PDC-L? Like you figure out all 3 of them and then just pick the biggest and that is True Range?

Please put this in the easiest terms possible without using math lingo to answer the question.

Yes, that is how I'd interpret it, from what you've written. Where did you find it?

Please do not double-post, and post your questions in a separate thread, as you have done here. I am deleting your other post and moving this topic into the Algebra sub-forum.
