HP 48G Series User Manual

Lesson 5: A Brief Tour of the HP 48
As compact and powerful as the stack is for manipulating objects,
there are many kinds of problem-solving situations which demand
special working environments tailored to specific needs. This lesson
takes you on a short tour of the various user-friendly environments
that comprise the HP 48.
Entry Environments
You have already seen the main entry environment on the HP 48—the
command line. However, among the mathematical objects handled by
the HP 48 are objects whose natural format is not well-suited to the
command-line display.
Creating Equations: @&) (EQUATION)
Algebraic equations and expressions can be entered as
you are accustomed to seeing them using a special entry
environment, the Equation Writer. The EquationWriter
is handy for writing any equation in a familiar form (see
lesson 6 for a worked example).
