Algebraic method
The HP 48 is as proficient with algebraic arithmetic as it is with
stack arithmetic. Unlike the direct, immediate 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 (* ') 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
((C)) is highlighted in the diagram to the left.
Example: Calculate . using the algebraic method.
Step 1: Enter the algebraic expression.
