5. የአሠራር መመሪያዎች
መሰረታዊ የሂሳብ ስራዎች፡-
Enter numbers and use the standard arithmetic keys (+, -, ×, ÷) followed by the equals key (=) to perform calculations.
- መደመር፡ [Number 1] [+] [Number 2] [=]
- መቀነስ፡- [Number 1] [-] [Number 2] [=]
- ማባዛት፡ [Number 1] [×] [Number 2] [=]
- ክፍል፡ [Number 1] [÷] [Number 2] [=]
Clear Functions:
- [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.
መቶኛtagሠ ስሌት፡-
በመቶኛ ለማስላትtages, use the [%] ቁልፍ
- Exampላይ: ከ200 ውስጥ 15% አስሉ።
አስገባ [200] [×] [15] [%]. The result will be 30. - Exampላይ: 15% ወደ 200 ያክሉ።
አስገባ [200] [+] [15] [%]. The result will be 230.
የግብር ስሌት፡-
The calculator features dedicated keys for tax calculations. First, set the tax rate.
- የግብር ተመኑን ማዘጋጀት፡
