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.
