WHY IS ZERO OUR HERO?
Sometimes we take our number system for granted, but it took many thousands of years to develop. Consider the Romans - for them recording and manipulating large numbers was cumbersome and near impossible.
Did you know the Romans recorded 3067 as MMMLXVII ! Imagine calculating using numbers like that!
The invention of zero allowed us to have a very streamlined number system. We can easily record infinitesimally large and small numbers and calculation is simple and efficient. So to recognize the amazing job zero does every day without us noticing, I think we should consider Zero Our Hero!
