Arithmetic
This calculator uses standard chaining logic, which simply means
that you enter your first value, the operator (
+ , – , x , ÷ ), the sec-
ond value and then the equals sign ( = ).
A. 3 + 2 = 5.00
B. 3 – 2 = 1.00
C. 3 x 2 = 6.00
D. 3 ÷ 2 = 1.50
Percentage Calculations
The Percent % key can be used for finding a given percent of a
number or for working add-on, discount or division percentage calcu-
lations.
A. 8 0 0 x 2 5 % = 200.00
B. 2 5 0 + 1 0 % = 275.00
C. 2 5 – 5 0 % = 12.50
D. 2 0 0 ÷ 5 0 % = 400.00
The Percent % key has special applications for real estate profes-
sionals — especially when figuring a commission amount.
Percent Change
If a home’s value increased from $315,000 (Present Value) to
$350,000 (Future Value), what is the percent increase?
STEPS KEYSTROKES DISPLAY
Subtract appreciated value
from the Present Value 3 5 0 ) – 3 1 5 ) =
35,000.000
Divide the difference by
the Present Value ÷ 3 1 5 ) = 0.11
Calculate percent increase x 1 0 0 = 11.11
(or 11.1%)
