Abstract: A multiplication abacus device is provided, which includes a main body with a result display area, where the result display area has calculation result bits arranged in a matrix, the calculation result bits have numbers for displaying a calculation result, a plurality of sliding members, arranged in a matrix that can slide horizontally and longitudinally on the main body, and located on the calculation result bits, where adjacent M rows of sliding members slide longitudinally, and adjacent N columns of sliding members slide horizontally. After the sliding members do not obstruct one row of calculation result bits and do not obstruct one column of calculation result bits, a number of the calculation result bits in a crossed position is a calculation result of M×N. Through the above technical solution, a technical problem of learning multiplication in existing technologies being abstract and not intuitive enough has been solved.
