Solving Your Own Equations (SOLVE)

This chapter has introduced some of the built-in menus the calculator offers. But if the solution to a problem is not built into hp 17bII+ , you can turn to the most versatile feature of all: the Equation Solver. Here you define your own solution in terms of an equation. The Solver then creates a menu to go with your equation, which you can use over and over again, just like the other menus in the calculator.

The Solver is covered in chapter 12, but here is an introductory example. Because equations usually use letters of the alphabet, this section also explains how to type and edit letters and other characters that aren’t on the keyboard.

Example:Using the Solver. Suppose you frequently buy carpet and must calculate how much it will cost. The price is quoted to you per square yard. Regardless of how you do the calculation (even if you do it longhand), you are using an equation.

Price per

Length (feet)

Width (feet)

square yard

 

 

 

P/YD ⋅ L ⋅ W

= COST

Converts square feet to square yards

To type this equation into the Solver, use the ALPHA menu.
