PROBLEM TO BE SOLVED: To build an abacus learning system wherein, while errors in bead-moving can be recognized after calculation, flexibility for bead-moving is allowed.;SOLUTION: An abacus learning system includes: a miscalculation information storage means 1F storing miscalculation information when model bead-moving information does not coincide with learner's bead-moving information by determining it as miscalculation; a correct/incorrect determining means 1G performing correct/incorrect determination on the basis of learner's answer information of the exercise collated by a bead-moving information collating means 1E and correct answer information stored in a model bead-moving information storage means 1B; a correct answer result information output means 1H outputting correct answer result information when the correct/incorrect determining means 1G determines that the learner's answer information coincides with the correct answer information; and a miscalculation information output means 1I outputting the miscalculation information stored in the miscalculation information storage means 1F when the correct/incorrect determining means 1G determines that the correct answer information does not coincide with the learner's answer information.;COPYRIGHT: (C)2010,JPO&INPIT
