After a few decades, an instrument with a modern frame and some beads connected to the rods was invented. This type of abacus still exists today. It is still in use in some Asian as well as Latin American countries. The Soroban abacus (Japanese) has become one of the valuable mathematical tools whereas. Schott (Russian) is also popular in most western countries.
