k 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.

(2+3)E2 does not produce the
correct result. Be sure to enter this calculation
as shown.

2
Final closed parentheses (immediately before
operation of the
w key) may be omitted, no
matter how many are required.
*
3
A multiplication sign immediately before an
open parenthesis may be omitted.
