Abstract

An electronic calculator makes a display section display an input mathematical expression when receiving an input of the mathematical expression from a user. At that time, a color is given to a component related to a predetermined operation symbol among components of the mathematical expression, and the component is displayed. Also a cursor is displayed in the same color as that of the component to which the cursor belongs. Thus, even when the mathematical expression is displayed in an arithmetic manner, each component of the mathematical expression and a position of the cursor can be easily distinguished from each other.

Dependent claims

An electronic calculator comprising:

a mathematical expression input section to receive an input of a mathematical expression from a user;
a mathematical expression display control section to display the mathematical expression input from the mathematical expression input section on a display section in an arithmetic manner;
a cursor display control section to display a cursor on the display section in a movable manner according to an operation of the user with respect to the mathematical expression displayed by the mathematical expression display control section;
a mathematical expression color process section to perform a color process for a component related to a predetermined operation symbol among components of the mathematical expression displayed by the mathematical expression display control section;
and
a cursor color process section to perform a color process for the cursor displayed by the cursor display control section such that the cursor is colored in the same color as a color of the component to which the cursor belongs.
