通常软件计算器模仿硬件计算器。它允许用户快速启动他们的工作与一个新的程序，因为用户已经知道如何使用他们的硬件计算器。但是，通过这种方法，在软件计算器的设计方面，它继承了硬件计算器的所有缺陷。例如： - 必须牢记在该优先级下单独输入的每个数字、运算符或函数。例如，如果在普通计算器表达式 2+2*2 中进行计算，则结果为 8，但如果计算 2*2+2，则结果为 6。当然，2+2*2 和 2*2+2 是等效的。这就是普通计算器引发错误的原因。 - 程序窗口以具有许多不必要的按钮的设备的形式绘制，输入和输出的单个指示器将在屏幕上占用大量 "quot;房地产"。 - 您不能将计算表达式输入公式，例如：123.32-12.4/sin（1/2） 每个数字、运算符或函数必须单独输入，彼此独立。 因此，您不能编辑以前输入的表达式。例如，您无法计算：123.32-12.4/sin （1/2） 和后 123.32-12.2/sin （1/2） 您必须重新输入所有公式，因为一个数字与另一个数字不同。 - 绘制的按钮会引发大量鼠标对输入的使用，但会大大降低表达式的输入速度。这对于计算是好事，但由于鼠标的使用，它确实会促进手部疲劳。对于必要的按钮搜索，需要永久重读按钮标题或记住最后一个按钮位置。 可扩展LibMaster.com是一种处理计算器设计的不同方法。因此，它不包含任何设计缺陷，如上所述。
