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
key (=).
A. 3 + 2 = 5.
B. 3– 2 =1.
C. 3 x 2 = 6.
D. 3 ÷ 2 = 1.5
This feature also makes the calculator sim-
ple to use for dimensional math.
Adding or Subtracting Dimensions
Examples:
KEYSTROKES DISPLAY
1. Add 7 Feet 3-1/2 Inches to 11 Feet 4
Inches:
7 f 3 i 1 / 2 +
1 1 f 4 i = 18
FEET 7-1/2 INCH
2. Add 25 psf to 12 psi:
2 5 Ç d + 1 2 Ç l =
PSF 1753.
3. Add 14 Gallons to 52 Liters:
1 4 g + 5 2 L =
GAL 27.73695
4. Subtract 450 Acres from 5 Square km:
5 K K – 4 5 0 Ç 5 =
3.178915
SQ kM
5. Subtract 32 mm from 8 Centimeters:
8 c – 3 2 M = 4.8 CM
