Abstract

A word processor having an arithmetic operation function has a character key keyboard for entering characters and numeric data and a function key keyboard for entering functions including operator codes of arithmetic operations. A numeral data to be arithmetically operated on is entered by the character key keyboard together with an operator code representative of an arithmetic operation to be executed on that numeric data, and the numeric data and the operator code are stored in a memory and displayed on a CRT screen so that the arithmetic operation required for the numeric data is identified on the CRT screen.
