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

= 500
( 2 + 3 )* 1 E 2 w *

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

(7 – 2) × (8 + 5) = 65

$ 6 c 4 * 5 w
(1 + 2
i ) + (2 + 3 i ) = 3 + 5 i (b+c ! a ( i ))+(c+
d ! a (

(2 +

1
( 2+ 3) E 2 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 .
