計算結果がスマホとアイパッドで異なります

963^2-214^2を計算するとスマホでは881,573と正しい結果になるのですが、アイパッドでは42,469,790,724と2項の積になります。

Excelente

Gran aplicación. No solo para científicos. Gran pantalla que va mostrando las operaciones anteriores hacia arriba y las puedes editar. Si editas arriba, al dar enter, muestra la operación y el resultado más abajo,manteniendo la operación editada arriba y editable, para comparar. Pantalla grande: es como una pizarra para trabajar. Pequeña publicidad no intrusiva. La pincho a veces para agradecer al programador. Demasiado buena!
