ABSTRACT:
When a user requested mathematical expression requiring, when normally displayed, a plurality of display rows is not an independent numerical element in another mathematical expression, for example, a numerator portion, the requested mathematical expression is displayed in a each textbook representation format with element of the mathematical expression positioned in a fixed manner on a predetermined display row. When a second mathematical expression is determined to be an independent numerical element in a first mathematical expression displayed in the textbook format, the independent numerical element is displayed in a one row linear representation format. As a result, it is possible to display in a display portion having a small number of display rows the entire mathematical expression requiring, when normally displayed, more rows in the vertical direction than display rows.
