Enlightenment abacus used for children to learn arithmetic

Abstract

The invention relates to an enlightenment abacus used for children to learn arithmetic. The enlightenment abacus comprises a frame, wherein the middle part of the frame is provided with a beam; the frame is divided into an upper part and a lower part by the beam; the installation holes are respectively reserved on the two inner sides of the frame; crosspieces are arranged in the installation holes; the middle parts of the crosspieces are penetrated through the beam; and the upper part and the lower part of each crosspiece are respectively sleeved with five upper beads and five lower beads. The upper part and the lower part of each crosspiece are respectively sleeved with five upper beads and five lower beads; each upper bead or lower bead only represents one; the children are more intuitive and easier to grasp when performing arithmetic by using the abacus; when performing add, subtract, multiply and divide operations, the operations can be performed not only from a high order to a low order, but also from the low order to the high order; and the enlightenment abacus used for the children to learn the arithmetic has the characteristics that: the structure is simple, the abacus is intuitive and convenient to operate, and the children are easy to learn and understand.

Description

Enlightenment abacus for children to learn arithmetic technical field The invention relates to an abacus, in particular to an enlightenment abacus for children to learn arithmetic. Background technique At present, most of the existing abacus is provided with 2 upper beads on each gear, each upper bead represents 5, and each gear is provided with 4 lower beads, each lower bead represents 1.
