4. Torolàlana miasa
4.1 Kajy fototra
Perform standard arithmetic operations:
- Fanampiny: Enter first number + laharana faharoa =
- Fanesorana: Enter first number - laharana faharoa =
- Fampitomboana: Enter first number × laharana faharoa =
- Diviziona: Enter first number ÷ laharana faharoa =
4.2 isan-jatotage Kajy
Kajy isan-jatotages:
- Example: To find 15% of 200: Enter 200 × 15 %30 ny vokatra.
- Example: To add 15% to 200: Enter 200 + 15 %230 ny vokatra.
