2. Historical facts  The number zero was invented by a man named Brahmagupta.  He was an Indian that wasn’t very keen on the old number system so he decided to make a new one and he thought of the number zero. I think the roman number system is unreliable and the calculations are not exact unless you spend a lot of time on it

3. What the internet thinks  The internet thinks that a lot of different people invented the new number system.  I just looked at the most frequent person and I think that this person is the one that invented the new number system. Brahmagupta.

5. the Expansion of math's  The new number system made it easer and faster for the human kind to do equation's.

6. What I think about it I think that this number system helps us by making solving equation's faster and easier. If we still used the old roman number system it would be a lot more harder.
