Finance buttons
Finance buttons enable you to find an unknown variable value based on 
a group of known variable values. For example, to calculate the monthly 
payment for a 30-year home loan of $100,000 with an annual interest 
rate of 8%, you would enter the following variables:
©Payments/year = 12
©N = 360 (30 years x 12 months)
©APR = 8
©PV = 100,000
©FV = 0
Using these variables, the answer would be -733.76 per month.
To solve this example:
1.
Enter a value...
