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
