Embodiment Construction

[0011] Such as figure 1 The shown addition and subtraction beads are composed of nineteen beads with string holes and beaded strings connecting the beads, and are characterized in that: each bead is marked with one of the Arabic numeral integers from 0 to 18 , the beads are arranged in order from small to large, and connected in series with a beaded rope, and each bead can move back and forth or rotate freely with the beaded rope as the axis.

[0012] Addition demonstration: first find the numbered "7" beads such as figure 2 , count 5 beads clockwise from the "7" bead to the "12" bead such as image 3 , the result is 12.

[0013] Subtraction demonstration: first find the numbered "15" beads such as Figure 4 , count 6 beads counterclockwise from the "15" bead to the "9" bead Figure 5 , the result is 9.

[0014] In addition to the above-mentioned implementation, the number of beads can be increased or decreased as required, and the arrangement can also be arranged from l...
