4. Betjeningsvejledning
4.1 Grundlæggende beregninger
Perform standard arithmetic operations:
- Tilføjelse: Enter first number + second number =
- Subtraktion: Enter first number - second number =
- Multiplikation: Enter first number × second number =
- Afdeling: Enter first number ÷ second number =
4.2 Procenttage Beregninger
For at beregne procenttages:
- Exampdet: To find 15% of 200: Enter 200 × 15 %Resultatet bliver 30.
- Exampdet: To add 15% to 200: Enter 200 + 15 %Resultatet bliver 230.

- Trykke TASTE SÆT igen for at gemme.
Once the tax rate is set:
- Tilføj moms: Indtast beløb SKAT+.
- Træk skat fra: Indtast beløb SKAT-.
4.4 Hukommelsesfunktioner
Use memory keys to store and recall values:
- M+: Tilføjer den viste værdi til hukommelsen.
- M-: Trækker den viste værdi fra hukommelsen.
- MR: Recalls the value stored in memory.
- MC: Clears the memory.
4.5 Square Root Calculation
To calculate the square root of a number:
- Indtast nummeret.
- Tryk på √ (square root) button.
Image 4.2: Close-up of the square root (√) button. This button is used for calculating the square root of a displayed number.
4.6 Time Calculations (H/M/S)
De H/M/S button allows for calculations involving hours, minutes, and seconds. This function treats numbers as sexagesimal (base 60) values for time-related arithmetic.
- Enter the hours, then press H/M/S.
- Enter the minutes, then press H/M/S.
- Enter the seconds, then press H/M/S.
- Perform desired operation (+, -, etc.) and press =.
