Casio fx-83 Using

Using the Casio fx-83 Calculator

The Casio fx-83 calculator is currently widely available and is highly

recommended for use by engineering students at Levels 2 and 3.

The calculator has over 250 functions and it incorporates a 'natural

display' that supports input and output using mathematical notation,

such as fractions, roots, etc.

INITIALISING THE CALCULATOR

The keystrokes shown in Figure 1 can be used to return the calculator's settings and modes

to their initial (default) values. Note that this operation will also clear any data from the

calculator's memory. The fx-83's Clear menu is shown in Figure 2.

The fx-83 provides three different calculation modes; COMP is used for general calculations,

STAT is used for statistical calculations, and TABLE is used to generate a table of values

based on a given expression. For Level 2, you will only need to use the COMP mode. The

Mode menu is shown in Figure 3 and the keystrokes required to set the calculator to the

COMP mode are shown in Figure 4.

Page 3 CONFIGURING THE CALCULATOR SETUP The fx-83 Setup menu allows you to control the way in which calculations are performed as well as the way that expressions are entered and displayed. The menu will let you work with a fixed number of decimal places (FIX), or with a fixed number of significant digits (SCI). You can also choose to use mathematical notation (MthIO) or conventional (line-based) notation (LineIO).
