Natural number can have or cannot have zero but zero may be considered as a Whole Number, a rational, real, an algebraic and also a Complex Number. If we want to calculate the number of zero in the given number then simply count zeros. We can write one crore as 107. Exponent in 107 is 7 which means that there are 7 zeros in one crore. Another method to write total number of zeros in one crore is to multiply 10 seven times. That is (10 * 10 * 10 * 10 * 10 * 10 * 10) which gives 10000000. Thus total number of zeros in one crore is 7 (seven). Various operations such as multiplication, subtraction, addition can be applied on zero.
