Abstract: A method of creating a mathematical or scientific expression on a computer system in which a user interface is provided on a computer display device. Input data comprising a string of alphanumeric characters is received from a keyboard. The input data is matched with one or more verbalisations of a mathematical or scientific term. The or each matching term is displayed on the display device. When a user selects one of the displayed matching terms a corresponding graphical symbol is displayed on the display device. The method allows the user to type a verbalised version of the desired mathematical or scientific expression and to have the corresponding mathematical or scientific notation displayed on the display device.
