Title:
ARITHMETIC UNIT AND METHOD THEREFOR AND MEDIUM FOR RECORDING ARITHMETIC CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP3711397
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To experientially learn the actual process of factorization without immediately displaying the arithmetic result of factorization in an arithmetic unit for operating the arithmetic display of the factorization.
SOLUTION: When a desired integral expression to be factorized is key inputted and displayed, and a 'factorization' key 12c is operated, a factorization menu for designating an arbitrary factor and selecting a factorization processing by either a binding processing or descending order arrangement is displayed. When an arbitrary factor for operating the descending order arrangement is input designated, and an 'execution' key 12d is operated, the inputted integral expression is factorized and displayed by the descending order arrangement processing based on the designated factor. On the other hand, when the arbitrary factor for operating the binding processing is designated, and an 'execution' key 12d is operated, the inputted integral expression is factorized and displayed by the binding processing based on the designated factor. Then, the factorizing processing by this factor designation can be stepwisely operated until an answer is obtained.
