This is a calculation training application for early elementary school years, a time trial of simple calculations composed of single digits: Add(no carry/with carry), subtract(no carry/with carry), multiply(1x/2x/.../9x) and divide. Calculation time records and numbers of miscalculations are stored in personal databases, and you can check the records and miscalculations later.
Changed some image and animation resources.
Screen on while calculating.
Fixed shutdown problem caused by SQLiteException.
