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+4.5-53w
56 × (–12) ÷ (–2.5) = 268.8
56*-12/-2.5w
(2 + 3) × 10
2
= 500
(2+3)*1E2w*
1
1 + 2 – 3 × 4 ÷ 5 + 6 = 6.6
1+2-3*4/5+6w
100 – (2 + 3) × 4 = 80
100-(2+3)*4w
2 + 3 × (4 + 5) = 29
2+3*(4+5w*

(7 – 2) × (8 + 5) = 65

$6c4*5w
(1 + 2
i) + (2 + 3i) = 3 + 5i (b+c!a(i))+(c+
d!a(i))w
(2 +
i) × (2 – i) = 5 (c+!a(i))*(c-!a(i)
)w

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.
