Abstract:
    A world general abacus is mainly is suitable for mathematical calculation. It can development the user intelligence and activate the user potency. The abacus includes an outer frame and gear rods which are equipped with beads. It is characterized in that: there can be 3 - 32 gear rods; and each gear rod is consecutively equipped with 9 beads. Compared with prior art, the utility model abacus meet a decade to get one when doing decimal system operation, because each gear rod is consecutively equipped with 9 beads; and each bead represents one. It directly solves the difficulty of full five plus breaking five or qui-complement number and mixing code; and it reduce 34 codes in prior art to 18 codes, which makes code application and saving rate reach to 47%. It is an uncommon breakthrough in understanding and applying the codes for learners. Besides, the utility model abacus has single direction and simple fingering when shifting the beads because the abacus is not equipped with transverse beam; so it can also correspondently enhance the operative speed.
