2-1 Basic Calculations

kArithmetic CalculationsEnter 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 = –25.523+4.5-53w
56 × (–12) ÷ (–2.5) = 268.856*-12/-2.5w
(2 + 3) × 102 = 500(2+3)*1E2w*1
1 + 2 – 3 × 4 ÷ 5 + 6 = 6.61+2-3*4/5+6w
100 – (2 + 3) × 4 = 80100-(2+3)*4w
2 + 3 × (4 + 5) = 292+3*(4+5w*2
(7 – 2) × (8 + 5) = 65(7-2)(8+5)w*3

*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.
