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.

1

(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.

4

This is identical to 6 / 4 / 5 w.
