Welcome to the PF.

Could you please define your acronyms and give more details? Can you give an example problem?

PW means present worth, AW means annual worth, and FW means future worth. They're methods that allow you to compare alternatives (the greater answer is the better alternative). But it's okay, I just found out that you can in fact use any of these methods to do it. Thanks though! :)
