Constant Calculations
• In constant calculations, the addend becomes a constant.
Subtraction and division are performed in the same man-
ner. For multiplication, the multiplicand becomes a con-
stant.
• When performing calculations using constants, constants
will be displayed as K.
34+57= 34 + 57 = 91.
45+57= 45 = 102.
68×25= 68 * 25 = 1’700.
68×40= 40 = 2’720.
