  1. THE NUMBER ZERO By: Shama Emma Mohamed

  2. Introduction This PowerPoint presentation is all about the Number Zero (0). In it you are going to learn about the History of Zero and many other facts. You are going to learn which culture really invented zero and about Fibonacci. I hope that you will enjoy my PowerPoint presentation.

  3. Historical Facts • Zero was the only number not represented by roman numerals • Zero was invented in India in the 5th century by Indian mathematicians • Zero derives from the Arabic word ‘sifr’ meaning in English ‘a secret way of writing’ and the English word is ‘cipher’ • Some people think that Zero was a well guarded secret in some countries, until it got known • The truth is it never even was a secret, it was just unknown to Europeans • Our number system is called the Hindu- Arabic number system, because India passed it on to the Arabs • Fibonacci also invented a number sequence called ‘Fibonacci sequence’

  4. More about the culture who invented zero India was the first culture to invent the number zero. They invented it in the 5th century. Later on other cultures used it and claimed it as their idea. Some people think that Indian astronomer Brahmagupta invented the number zero.

  5. Introduction of zero to Europe It took them a full five centuries to introduce zero to Europe. Before that many mathematicians (the most popular ones: Leonardo Fibonacci and Al-Khowarizmi) gave zero a great many names and shapes. When it reached Europe it took on the shape of an oval , but zero still has many different names in many different language-speaking countries. Zero got introduced in 1200 when Fibonacci introduced them to Europe to 1700 when they became popular. This is how numbers developed. In Brahmi times they didn’t even have the number zero.

  6. Leonardo Fibonacci Leonardo Fibonacci aka. Leonardo of Pisa or Leonardo Pisano was born in Italy, Pisa somewhere around 1175AD. His father was Guilielmo Bonacci a secretary at the Republic of Pisa. He bought the number zero to Europe in the 1200 BC. He was one of the greatest mathematicians that ever lived. He died in the 1250’s. There is a statue commemorating him at the Leaning Tower of Pisa. Leonardo Fibonacci

  7. Expansion of Math There is now only one question left to answer: HOW DID THE NUMBER ZERO HELP MATHS? Well the number zero helped math, because you could now make larger numbers e.g. 100. Also you could have more math problems to solve. Before we invented the number zero we only had numbers 1-9. The Hindu Arabic number system has helped us a lot.

  8. Concluding Summary I hope that you have learned about the number zero and its origin. Remember that there are still some unknown things about zero. For the sources check my BIBLIOGRAPHY. The number zero is very useful in everyday life for buying and selling. I hope that you have enjoyed my PowerPoint presentation a lot.
