Abacus is a word with which the parents of children of the age between 5 t0 14 are fairly acquainted these days. This has happened as the several players in the market have opened up their abacus franchisee centers in all the major cities of India.
The above is true, but another fact that is true is that there are not many National of Multinational players in the field of abacus in India.
As per the available data there could be more than 200 companies in the field of abacus. They have limited themselves to selected states of India. Mastermind Abacus is also one of them in Indore, India.
