ENTERING DIMENSIONS
Linear Dimensions
When entering Feet-Inch values, enter
dimensions from largest to smallest — Feet
before Inches, Inches before Fractions.
Enter Fractions by entering the numerator
(top number), pressing /(Fraction Bar
key) and then the denominator (bottom
number).
Note: If a denominator is not entered, the frac-
tional setting value is used.
Examples of how linear dimensions are
entered (press oafter each entry):

BASIC MATH OPERATIONS
Your calculator uses standard chaining
logic, which simply means that you enter
your first value, the operator (+, -, x,
÷), the second value and then the Equals
sign (=).
A. 3 + 2 = 5.
B. 3-2=1.
C. 3x2=6.
D. 3÷2=1.5
This feature also makes the calculator
simple to use for dimensional applications:
Adding and Subtracting Strings of
Dimensions
Add the following measurements:
• 6 Feet 2-1/2 Inches
• 11 Feet 5-1/4 Inches
• 18.25 Inches
Then subtract 2-1/8 Inches.

20f3i÷9= 2 FEET 3 INCH
PERCENTAGE CALCULATIONS
The %key can be used for finding a given
percent of a number or for working add-on,
discount or division percentage calcula-
tions. It can be used with any type of
number, in any dimension (Feet, Inch,
Millimeter, etc) and any type of convention
(non-dimensioned, Linear, Square or Cubic).

Using Memory Storage Keys (M1 - M3)
In addition to the standard cumulative
Memory (as previously described), your
calculator has three independent Storage
Registers – M1 through M3 – that can be
used to permanently store single, noncu-
mulative values. The following example
shows the use of M1 (S1). To use M2
or M3, replace the presses of the 1key
with presses of the corresponding number
key (2or 3).
Your can replace a value in one of these
Memory registers by storing a new value in
place of the stored value.
