Hasun Designed by Qian Haosun in 1984 Chinese mathematicians
developed a counting system based on tens in 300 BC. The abacus,
an early calculator, may have been invented to speed up their
calculations and can assist with additions, subtractions,
multiplications and divisions. Qian Haosun, a Taiwanese artist,
designed this wooden framed abacus with metal rods and porcelain
beads decorated with dragons in 1984. Abacuses are still in use
in China, Taiwan and Japan.
