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.
Example Operation Display
23 + 4.5 – 53 = –25.5 23+4.5-53w –25.5
56 × (–12) ÷ (–2.5) = 268.8 56*-12/-2.5w 268.8
(2 + 3) × 10

= 500 (2+3)*1E2w*

3 × 4 ÷ 5 + 6 = 6.6 1+2-3*4/5+6w 6.6
100 – (2 + 3) × 4 = 80 100-(2+3)*4w 80
2 + 3 × (4 + 5) = 29 2+3*(4+5w*

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