5. Upute za rad

Osnovne aritmetičke operacije:

Enter numbers and use the standard arithmetic keys (+, -, ×, ÷) followed by the equals key (=) to perform calculations.

• Dodatak: [Number 1] [+] [Number 2] [=]
• Oduzimanje: [Number 1] [-] [Number 2] [=]
• Množenje: [Number 1] [×] [Number 2] [=]
• Podjela: [Number 1] [÷] [Number 2] [=]

Jasne funkcije:

• [CA/C] (All Clear): Clears all entries and memory, resetting the calculator.
• [CE] (Clear Entry): Clears the last entered number or the current calculation result without affecting previous entries or memory.

Percentage Izračun:

Za izračun postotakatages, use the [%] ključ.

• Exampono: Calculate 15% of 200.
  Uđi [200] [×] [15] [%]Rezultat će biti 30.
• Exampono: Add 15% to 200.
  Uđi [200] [+] [15] [%]Rezultat će biti 230.

Obračun poreza:

The calculator features dedicated keys for tax calculations. First, set the tax rate.

1. Određivanje porezne stope:
   Unesite poreznu stopu (npr. [8] for 8%). Press [RATE SET]. The tax rate is now stored.
2. Dodavanje poreza:

• [CM] (Clear Memory): Clears the memory content. (Often combined with RM, pressing RM twice clears memory).

Izračun kvadratnog korijena:

To calculate the square root of a number, enter the number and then press the [√] ključ.

• Exampono: Calculate the square root of 81.
  Uđi [81] [√]Rezultat će biti 9.
