PURPOSE:To input a complex numerical formula with simple operation and to make a numerical formula displayed on a screen coincide with a real image to make input check or correcting work easy by using display code corresponding to a symbol pattern for a numerical format code. CONSTITUTION:In case of inputting a matrix and a root formula written in an input original 10, a display code data input means 1 for inputting parentheses symbols ( ) of the matrix or a root symbol sq. rt. is used. In case of a matrix, the data of the matrix are written in a data storing means 12 by inputting a left parenthesis symbol, data and a right parenthesis symbol successively. A pattern generating means 13 reads out the contents of the data storing means 12 successively, executes the pattern processing of numerical formats correspond ing to the read data and outputs the formed dot pattern data to a display means 14 to display the data on its screen.
