I've been using Microsoft spreadsheets for a long time now but I'm trying to find a better program and one with more formulas. I heard about a program called Iworks but was wondering it anyone has used this program to find out if it is any better than Microsoft.

It's an Apple-only application, so if you use a Mac, go to

Apple - Downloads (http://www.apple.com/downloads)

And download a free trial. Then you can decide for yourself.
