All those calculated numbers in Column C are interesting, but maybe you want to Hide that column to present a more simplified look.  Un-hide it when you want to see the numbers.  To hide Column C, just RightClick at the top of Column C, then select Hide.  To un-hide it, just click on the two small arrows between Column B and D (right where C is hiding).  Take a look:

After, with Column C hidden:  Cleaner, right?
