Identifying Parts

As you launch Expression Calculator, it shows a fully featured user-interface. The interface has been designed to look like any normal calculator. Hence, it resembles a Casio fx-4500P calculator, which, by the way, unlike its Hewlett Packard, extremely powerful, but fairly complicated rivals, always insisted on avoiding the inverse polish notation and constructs as such. It allowed to enter simple natural expressions, very much like the Expression Calculator.

You will easily identify the following parts:

• Results Grid

• Input Box

• Results Panel

• Modes Panel

• Functions Panel

• Operations Panel
