Zero? Here, We have 7 interesting questions. 1. If Aryabhatta invented 0 then how do we know that Ravana had 10 heads? Ans: This is one of the biggest misconceptions in India. It has created a huge confusion among the Indians. Aryabhatt never invented or discovered zero! He invented a unique symbol for the mathematical purpose. Zero existed even before Aryabhatta created it as a symbol ‘0’. Zero was referred to as Shunya in Vedic times. It was always there, the counting systems. The counting systems were in words not as symbols. Our Hindu calendars and for that matter Muslim calendars has numbers.
