Oppo How to Use Calculator
Oppo 15Scientific calculator
The pocket calculator on the Oppo smartphone has long since ceased to be able to calculate only 1+1, and its further development has already given it some scientific functions such as the angular functions sine (sin), cosine (cos) and tangent (tan).
The calculator can also be used as a currency converter or as a general converter for units of measurement:
- Length
- Area
- Volume
- Speed
- Weight
- Temperature
- Performance
