ENTERING DIMENSIONS
inear 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 denomina-
tor (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 sim-
ple to use for dimensional applications.
