New to Excel

Good Day,

I'm new to Excel, am using Excel 2010.

I've 30+ years in IT services, mostly developing software using database tools under UNIX. But Very Little exposure to Excel.

I'm retired but working part time for a friend, helping to better integrate the accounting system with his business.

One of my goals is to provide my friend with better tools for planning and decision making.

Regards,
Dan Rosencrance
