Abstract
A mathematical expression input apparatus which is capable of inputting and displaying a mathematical expression efficiently by automatically determining whether or not an element inputted to a displayed input position of a functional expression can be recognized as a complete argument without instructions from the user. In the case of inputting an exponent of a power calculation, it is determined that the input of the argument is complete when a predetermined number of digits such as the second digit is inputted in an exponent display position thereby automatically moving a cursor from the exponent display position to a normal display line position. In addition, for example, in the input of an element in a root symbol where a left bracket is first inputted. It is then determined that the input of the argument is ended with the input of a right bracket which automatically moves the cursor from the inside of the root symbol to the normal display line position adjacent to the root symbol. Thus the cursor is automatically moved in the respective situations to the normal display line position without an additional instruction from the user.
