2-1 Basic Calculations

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 × (–12) ÷ (–2.5) = 268.8 56*-12/-2.5w 268.8

(2 + 3) × 10

= 500 (2+3)*1E2w*

500

1 + 2 – 3 × 4 ÷ 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*

(7 – 2) × (8 + 5) = 65 (7-2)(8+5)w*

= 0.3 6 /(4*5)w*

0.3

4 × 5

“(2+3)E2” does not produce the correct result. Be sure to enter this calculation as

shown.

The final closed parentheses (immediately before operation of the w key) may be omitted,

no matter how many are required.

A multiplication sign immediately before an open parenthesis may be omitted.

This is identical to 6 / 4 / 5 w.
