kArithmetic 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) ⋅ 102 = 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*2

(7 – 2) ⋅ (8 + 5) = 65

(7-2)(8+5)w*3

6

= 0.3

*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.
