(phi+1/phi)^2=5 as my Spreadsheet Shows





    
Binomial Theorem

Pascal's Triangle




"Mortgage terms are usually 15 or 30 years.
The longer the term, the lower your monthly payment,
but the higher your overall interest costs."



So says Mortgage Basics - Real Estate Guide on Yahoo! Personal Finance.

My spreadsheet can be used to calculate the "overall interest costs". Try the "Interest" sheet.




    

This is Pascal Triangle Pro. It has lookup functions for binomial coefficient and shows Fibonacci numbers in the triangle.
