Arithmetic Calculations
• Enter arithmetic calculations as they are written, from left to right.
• Use the
-
key to input the minus sign before a negative value.
• Calculations are performed internally with a 15-digit mantissa. The result is rounded to a
10-digit mantissa before it is displayed.
• For mixed arithmetic calculations, multiplication and division are given priority over
addition and subtraction.
