These tutorials assume that you already understand the fundamentals (math and terminology) of the time value of money.  They only deal with time value of money calculations — I do not cover any other functions of your calculator. 

I also have a tutorial that shows how to use Microsoft Excel (or any other spreadsheet) to solve the same problems as you might on a financial calculator. Finally, if you don't currently own a calculator, you should definitely check out How to Choose a Financial Calculator.

Should you discover any errors please let me know via e-mail.
