10 Interesting Facts about Zero

All mathematicians must have described and found one of these following facts about zero really useful for their research, especially for those who are in mathematician major on college. Zero, a number, is both 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 structure. As a digit, “0” (zero) is used as a placeholder in place value systems. To get to know much more about this number, here are some interesting facts about zero you may like.
