HP 17bII manual Calculations Using Menus

Calculations Using Menus

Using menus to do calculations is easy. You don’t have to remember in what order to enter numbers and in what order results come back. Instead, the menus guide you, as in the previous example. All the keys you need are together in the top row. The menu keys both store numbers for the calculations and start the calculations.

The MU%C menu can calculate M%C, the percent markup on cost, given COST and PRICE.

Then the same menu can calculate PRICE given COST and M%C.

Notice that the two calculations use the same three variables; each variable can be used both to store and calculate values. These are called built-in variables, because they are permanently built into the calculator.
