5. Treoracha Oibriúcháin
Oibríochtaí Bunúsacha Uimhríochta:
Enter numbers and use the standard arithmetic keys (+, -, ×, ÷) followed by the equals key (=) to perform calculations.
- Suimiú: [Number 1] [+] [Number 2] [=]
- Dealú: [Number 1] [-] [Number 2] [=]
- Iolrú: [Number 1] [×] [Number 2] [=]
- Rannóg: [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.
Percentage Ríomh:
Chun céatadán a ríomhtages, use the [%] eochair.
- Example: Calculate 15% of 200.
Cuir isteach [200] [×] [15] [%]. The result will be 30. - Example: Add 15% to 200.
Cuir isteach [200] [+] [15] [%]. The result will be 230.
