2-1 Basic Calculations
k k k k 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
Ч (–12) ч (–2.5) = 268.8
56*-12/-2.5w 268.8
(2 + 3)
× 10 2 = 500 (2+3)*1E2w* 1 500
1 + 2 – 3
Ч 4 ч 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 29
(7 – 2)
× (8 + 5) = 65 (7-2)(8+5)w* 3 65
6
= 0.3 6 /(4*5)w* 4 0.3

* 1 “(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.
