5. عملیاتي لارښوونې

اساسی ریاضی عملیات:

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

• اضافه: [Number 1] [+] [Number 2] [=]
• تخفیف: [Number 1] [-] [Number 2] [=]
• ضرب: [Number 1] [×] [Number 2] [=]
• څانګه: [Number 1] [÷] [Number 2] [=]

پاکې دندې:

• [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.

پرسینtage محاسبه:

د فیصدي محاسبه کولو لپارهtages, use the [%] کلید

• ExampLe: Calculate 15% of 200.
  ننوتل [200] [×] [15] [%]. پایله به ۲۲ وي.
• ExampLe: Add 15% to 200.
  ننوتل [200] [+] [15] [%]. پایله به ۲۲ وي.

د مالیاتو محاسبه:

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

1. د مالیې کچه ټاکل:
   Enter the tax rate (e.g., [8] for 8%). Press [RATE SET]. The tax rate is now stored.
2. د مالیې اضافه کول:
   Enter the amount (e.g., [100]). مطبوعاتي [+TAX]. The display will show the amount with tax added.
3. د مالیې کمول:
   Enter the amount (e.g., [108]). مطبوعاتي [-TAX]. The display will show the amount with tax removed.
4. د مالیې بیرته راګرځولو کچه:
   مطبوعاتي [RATE RECALL] ته view د مالیې اوسنی ټاکل شوی نرخ.

د حافظې دندې:

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

• [M+] (Memory Plus): ښودل شوی ارزښت حافظې ته اضافه کوي.
• [M-] (Memory Minus): ښودل شوی ارزښت له حافظې څخه کموي.
• [RM] (Recall Memory): هغه ارزښت ښیې چې اوس مهال په حافظه کې ساتل شوی دی.
• [CM] (Clear Memory): Clears the memory content. (Often combined with RM, pressing RM twice clears memory).

د مربع ریښې محاسبه:

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

• ExampLe: Calculate the square root of 81.
  ننوتل [81] [√]. پایله به ۲۲ وي.

6. ساتنه

• پاکول: Use a soft, dry cloth to clean the calculator's exterior. For stubborn dirt, slightly dampen the cloth with water and a mild detergent, then wipe dry immediately. Do not use abrasive cleaners or solvents.
