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
23 + 4.5 – 53 = –25.5
56 × (–12) ÷ (–2.5) = 268.8
2
(2 + 3) × 10
= 500
1 + 2 – 3 × 4 ÷ 5 + 6 = 6.6
100 – (2 + 3) × 4 = 80
2 + 3 × (4 + 5) = 29
(7 – 2) × (8 + 5) = 65
