Calcolatrice per pad

Ho provato tutte le calcolatrici in commercio e ho avuto vari problemi. Abbiamo creato una calcolatrice che potrebbe essere più facile da usare. Le caratteristiche principali sono le seguenti:
1. Nessun annuncio, nessun annuncio verrà aggiunto in futuro
2. Supporta calcoli semplici e calcoli scientifici
3. È possibile visualizzare i passaggi di calcolo e il processo di calcolo
4.Supporta la visualizzazione maiuscola cinese
5. Ottimizzato per Pad ad alta risoluzione
6. Dimensioni molto ridotte senza occupare spazio di archiviazione
