Formula Entry I - Sharp EL-5100 Instruction Manual

DIRECT FORMULA ENTRY (AER)
(ALGEBRAIC EXPRESSION RESERVE)
With AER a formula can be stored as an algebraic expression. The formula, even if complicated is entered as
you would read it. The rolling writer dot matrix liquid crystal display makes it possible to enter up to 80 steps
with no lim it on characters.
1. Formula Entry I
In Section 6 of the discussion on the COMP Mode, entering a formula was demonstrated. However, if it
was required to do other calculations in the COMP MODE, the equation would be lost. To retain a formula
so that we may use it over and over the AER Mode is used.
Put the calculator in the AER mode. Clear the display by pressing (2nd F) l
CAl
(above Red CL Key).
Your display will show 1; which means Line 1 (Lines w ill be discussed in a later section.)
Key in: A 2 C B B2
To solve this equation move the black mode switch to COMP.
