A mathematical training system includes an electronic abacus device. The sequence of operating counter beads of the abacus is converted to data signal by sensors . The data signals are outputted to a computer device having a monitor display for showing the operation of an instructor's abacus as well as a student's abacus. The student's operation i s recorded such that it may be reviewed in any selected time by the instructor to assess whether the student has operated the abacus correctly to arrive at the solution of a mathematical assignment. The computer may also provide a warning and a corrective operation to the student when an erroneous manipulation is detected.
