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 but I just looked at the most frequent person and I think that that person is the one that invented the new number system.

4. Introduction to Europe

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 because if we still had the old number system we wouldn’t be able to get an answer as fast as we can now because of no number zero.

7. Summary  Thank you for listening to my presentation and I hope you enjoyed it.
