Note: The calculator may power on automatically once sufficient light or battery power is detected.

5. Istruzzjonijiet Operattivi

Operazzjonijiet Aritmetiċi Bażiċi:

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

• Żieda: [Number 1] [+] [Number 2] [=]
• Tnaqqis: [Number 1] [-] [Number 2] [=]
• Multiplikazzjoni: [Number 1] [×] [Number 2] [=]
• Diviżjoni: [Number 1] [÷] [Number 2] [=]

Funzjonijiet Ċari:

• [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.

Perċenswalitage Kalkolu:

Biex tikkalkula perċentwaltages, use the [%] ċavetta.

• Example: Calculate 15% of 200.
  Daħħal [200] [×] [15] [%]. The result will be 30.
• Example: Add 15% to 200.
  Daħħal [200] [+] [15] [%]. The result will be 230.

Kalkolu tat-Taxxa:

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

1. L-Istabbiliment tar-Rata tat-Taxxa:
   Enter the tax rate (e.g., [8] for 8%). Press [RATE SET]Ir-rata tat-taxxa issa hija maħżuna.
2. Żieda tat-Taxxa:
   Enter the amount (e.g., [100]). Agħfas [+TAX]. The display will show the amount with tax added.
3. Tnaqqis tat-Taxxa:
   Enter the amount (e.g., [108]). Agħfas [-TAX]. The display will show the amount with tax removed.
4. Recalling Tax Rate:
   Agħfas [RATE RECALL] biex view the currently set tax rate.

Funzjonijiet tal-memorja:

The 4-key memory allows you to store and recall values.

• [M+] (Memory Plus): Iżżid il-valur muri mal-memorja.
• [M-] (Memory Minus): Inaqqas il-valur muri mill-memorja.
• [RM] (Recall Memory): Juri l-valur li bħalissa huwa maħżun fil-memorja.
• [CM] (Clear Memory): Clears the memory content. (Often combined with RM, pressing RM twice clears memory).

Kalkolu ta' Għerq Kwadru:

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

• Example: Calculate the square root of 81.
  Daħħal [81] [√]. The result will be 9.

6. Manutenzjoni

• Tindif: Use a soft, dry cloth to clean the calculator's exterior. For stubborn dirt, slightly dampLaħlaħ id-drapp bl-ilma u deterġent ħafif, imbagħad imsaħ niexef immedjatament. Tużax prodotti tat-tindif jew solventi li joborxu.
