GETTING STARTED
You may want to practice getting a feel for
your calculator keys by reading through the
key definitions and learning how to enter basic
feet-inch-fractions and metric values, how to
store values in Memory, etc., before proceed-
ing to the examples.
Also review specific default settings or prefer-
ence settings.
Order of Operations
Unlike other Calculated Industries calculators,

which use the Chaining Method of Operations,
this calculator uses the Order of Operation
Method.
● Chaining Method (“as entered”):
10 + 4 x 5 = 70
● Order of Operations: 10 + 4 x 5 = 30
The Order of Operations method of computing
is based on the following order of precedence:
1) Expressions inside of parentheses
2) Single-variable functions that perform
the calculation and display the result
immediately (trig functions, square,
square root, x
y
, percent, reciprocal,
angle conversions)
3) Multiplication and division
4) Addition and subtraction
5) Equals (completes all operations)
If you need to calculate using the Chaining
Method, you can change this in your calculator
Preference Settings.
Using Parentheses
Your calculator has parenthesis keys and 
for performing mathematical operations. In the
Order of Operations method, expressions inside
of parentheses are performed first.
POCKET REFERENCE GUIDE —7

The calculator offers up to 21 levels of parentheses:
1) First parenthesis level opened – press
for one right-sided parenthesis.
2) Second level opened – press a
second time for two right-sided
parentheses .
3) Third level opened – press a third
time for three right-sided
parentheses .
4) Fourth level opened – press a fourth
time for four right-sided parentheses
.
Numbers of levels greater than four are shown
in the upper left corner of the display.
