Some of my friends ask me, if you are taking the entire Hindi language, and when some of the numerals more or less similar, why not accept a few more? It is not a question of learning three or four numerals. I believe every one will know the Hindi numerals, which may be also used right from the beginning. Hindi numerals will also be learnt by all. But the question is regarding their use for purposes for which you consider they cannot be properly used.
