He estado usando Excalibur durante años. Es una excelente calculadora. Tiene un tamaño muy pequeño, una interfaz razonable, independiente (es decir, se mantiene fuera del registro de Windows). La notación polaca inversa en realidad funciona de la misma manera que las personas. Cuando agrega dos números, conoce los números de antemano y agrega ellos. Por ejemplo, cuando sumas 3 a 4 realmente operas (3, 4) +. Así es exactamente como funciona RPN. Usted ingresa los dos números y luego los agrega. La notación "algebraica" (como PhD en Álgebra Abstracta, no me gusta ese nombre) cambia el significado de = de 'igual a' hace ' . Yutch.
It is not a RPN calculator. It does not run on Windows.
