A power point made by Ashnee Rajani 7BRM

Introduction Hello as all of you know my name is Ashnee Rajani and I am in Year 7BRM. As you know this slide show is about the number zero and I am going to put all the facts we have to include. My power point has 8 slides with different titles. I HOPE YOU ENJOY!!!

Historical facts The first point is that the number zero was invented in India. The Mayan civilization may have been among the first to have a symbol for zero. The Greeks made great strides in mathematics, but it was all done with a number system without zero. Throughout the Dark Ages, Western mathematics was held back by the Roman's traditional numbering system. The first to think differently was Leonardo Fibonacci. He was a merchant's son, born in the Italian city-state Pisa, late in the twelfth century.

Etc… Historical Facts In the sixth century, mathematicians in India developed a place-value system. They introduced the concept of zero to keep their symbols in their proper places. In the seventh century, Hindu scholars introduced to Islam the ideas of zero and place-value. These ideas spread rapidly throughout the Arabic world. People say the number zero was invented by Aryabhatta in India. Wow India is famous!!!

Introduction to Europe They were transmitted to Europe in the Middle Ages. The use of Arabic numerals spread around the world through European trade, books and colonialism. Today they are the most common symbolic representation of numbers in the world. As befitting their history, the digits (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9) are known as Hindu numerals or "Hindu-Arabic numerals". The reason they are more commonly known as "Arabic numerals" in Europe and the Americas is that they were introduced to Europe in the 10th century by Arabs of North Africa, who were then using the digits from Libya to Morocco.

Etc… Introduction to Europe Europeans did not know about the numerals' origins in ancient India, so they named them "Arabic numerals.“ In English, the term Arabic numerals can be ambiguous. It most commonly refers to the numeral system widely used in Europe and the Americas. Arabic numerals is the conventional name for the entire family of related systems of Arabic and Indian numerals.

Expansion of math's My Perspective- Well I think it has changed math’s a lot because now almost the whole world is using the number zero in math’s because they have got used to it. They used it for fractions, decimals anything. My Research- The number zero fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. In the English language. So it has gotten over the whole world and is much easier for people to use. They don’t have much complaints.

How the ancients used numbers? Well the ancients used numbers in many ways because everyone then had different number systems like the Roman, Greek, Egyptian. Some used numbers with alphabets which were also letters. Some different number system consisted Different shapes like spirals, men walking. There were many ideas. There were also finger systems.

Different number systems.

Concluding summary Well at the end of all this I have learnt a lot especially to how the number zero was introduced to Europe. Cause now I know how they got use to it. I also learnt of how to create a number system of your own cause I know it kind of is hard. Another thing I also learnt which is the unit question of how the ancients actually used numbers. It was quite hard at answering it first.
