Who is John Napier bone?

John Napier (1550-1617), discoverer of logarithms, also created this popular calculating tool known as Napier’s cylindrical ‘rods’ or ‘bones’. Napier’s bones reduced muliplication to a sequence of simple additions and could also be used for division and to calculate square roots.

Who invented 0 in India?

Is zero a number Yes or no?

0 (zero) is a number, and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.
