Arithmetic Calculations
Arithmetic calculations can be used to perform addition (
+
), subtraction (
-
),
multiplication (
*
), and division (
/
).
Example: 7 × 8 − 4 × 5 = 36
7*8-4*5

Note
• If the total number of elements (integer + numerator + denominator + separator symbols)
of a fraction calculation result is greater than 10 digits, the result will be displayed in
decimal format.
• If an input calculation includes a mixture of fraction and decimal values, the result will be
displayed in decimal format.
• You can input integers only for the elements of a fraction. Inputting non-integers will
produce a decimal format result.
