Basic Calculations

Unless otherwise noted, the calculations in this section can be performed in any of the calculator’s calculation mode, except for the BASE Mode.

kArithmetic Calculations

Arithmetic calculations can be used to perform addition (+), subtraction (-), multiplication (*), and division (/).

Example 1: 2.5 + 1 − 2 = 1.5

2.5+1-2w

Example 2: 7 × 8 − 4 × 5 = 36

7*8-4*5w
