Abstract
A mathematical expression display control apparatus includes a mathematical expression input unit, a mathematical expression display control unit, a cursor display control unit, an inverse number function input unit, an inverse number target detection unit and an inverse number display control unit. The mathematical expression input unit recognizes a mathematical expression. The mathematical expression display control unit displays the recognized mathematical expression on a display unit. The cursor display control unit moves and displays a cursor in the displayed mathematical expression. The inverse number function input unit recognizes an inverse number function. The inverse number target detection unit detects a chunk region of the mathematical expression as a target of the inverse number function. The inverse number display control unit replaces the detected chunk region with a fraction having the detected chunk region as a denominator and 1 as a numerator to display.
