Algebraic method

The HP 48 i.s as proficient with algebraic arithmetic as it. is with

stack arithmetic. Unlike the direct, immediat.e approach of stack

arithmetic, the HP 48 also allows you to enter a computation as an

algebraic formula so that you can inspect it or store it for later use.

This method also has two steps: first create and enter the formula,

then evaluate it to compute the result.

You must surround an algebraic formula with

tick-marks (' C so that the HP 48 understands that you

want to treat the mathematical operations as a formula

instead of as a series of direct commands. The “tick” key

(CD) is highlighted in the diagram to the left.

Example:

Calculate ©g using the algebraic method.

Step 1: Enter the algebraic expression.

___

'j--62.5'

Step 2: Evaluate the expression to obtain a numerical result.
