Abstract

It is an object of the invention to provide an electronic computing apparatus having an arithmetic processing function and an arithmetic processing method which allow an arithmetic expression to be readily inputted. A screen showing stored contents of an arithmetic expression menu table is displayed by specifying an arithmetic expression menu display command key. Then, selecting an arithmetic expression from the displayed plurality of arithmetic expressions by an input pen allows the selected arithmetic expression to be inputted. A controller executes arithmetic processing in accordance with the selected arithmetic expression and displays the result of the arithmetic processing as a graph on the display. Accordingly, the arithmetic expression may be readily inputted just by selecting the arithmetic expression from the predetermined plurality of arithmetic expressions. Further, the desired arithmetic expression may be inputted while watching all the arithmetic expressions because the arithmetic expression menu table is displayed.
