__ My Investigation for unit 5 __


 * How did the ancients use numbers? **

Name the man who brought it to Europe? 5. Describe what was wrong with the roman numerals number system?
 * 1. ** Where did the number Zero come from?
 * 2. ** When did it spread to Europe? ** 3. **
 * 4. ** What city in Italy first used the number Zero?
 * 6. ** Why were people afraid of the new number system?
 * 7. ** Contrast the roman numerals to the new number system
 * 8. ** What difference did the new number system make in Europe?
 * 9. ** Plan your own number system. ** 10. ** How could the number Zero been invented in two different parts of the planet by two totally unrelated civilisations at about the same time?

1, Zero is the inventions of Indians. 2, the number zero spread to Cambodia around the end of the 7th century. From India it moved into China and then to the Islamic countries. Zero reached Western Europe in the 12th century. []

3. His name was Arhiyabhata. 4,

5, we stopped using roman numerals a lot because Roman numerals were inefficient - to write 88 you would need to write LXXXVIII. This was too long. Roman numerals were too long to use so society conformed to use a new and easier number system. 9. 1 = hy 2 =hyy 3 =hyyy 4 = wdd 5=wer 6=ct 7=iuy 8=uyt 9=uu 10=dixy Zero traveled over the World due to various travelers from England & UK countries.

Investigation

Zero traveled over the World due to various travelers from England & UK countries. Zero has unique importance in Maths & Technology The number 0 is the smallest non-negative integer. The natural number following 0 is 1 and no natural number precedes 0. The number 0 [|may or may not be considered a natural number], but it is a whole number and hence a rational number and a real number (as well as an algebraic number. The number 0 is neither positive nor negative and appears in the middle of a [|number line]. It is neither a prime number nor a composite number. It cannot be prime because it has an [|infinite] number of factors and cannot be composite because it cannot be expressed by multiplying prime numbers (0 must always be one of the factors). Zero is, however, even (see parity of zero). The concept of the zero spread through the Arabian nations, through North Africa and through Europe through trading. Zero was called sunyaa in Sanskrit, meaning void. When the symbol came to the Arabs, œsunya was translated into the Arabic safira. The person generally credited to have brought the idea of zero to Europe was the mathematician and philosopher Fibonacci, the author of the mathematical concept Fibonacci’s Square. Fibonacci grew up in the Arabic North Africa. He translated the Arabic safira to zephyrum. Zephyrum became zefiro in Italian, and the Venetians further contracted the word into Zero.

__ Investigation __

=__ Unit question: __ How did the ancients use numbers? = =__ The problem: __ The problem is I don’t know how ancient people used their number system. It might even be so different from the number system we have today. Over generations the number system must have changed and is now simpler than the ancient number system. How people long time ago used their number system and how they understood it. I have to try and understand their number system have to find out how they used their number system. =

=__ Investigation: __. = = For the Greeks number system they used an abacus. The Greeks used their hands for their numbers as well as an abacus. Tallying (by making lines standing for individual animals) in the dirt or sand was an early form of counting fingers and would carry on been used when a shepherd or other animals had 10 t0 watch. Roman numerals have been a way of permanently recording tallies. = = At some point in time making marks in the ground with a stick was going to eventually lead to the abacus. = []

__Mayans __

For the Mayans number system they used their hands and feet. The Mayans number system was based on 20. The Mayans used 20 as the total number of fingers and toes because this was because the number system was easy to work with. There were two important markers in this 20, which relates to the fingers and toes, and five, which relates to the number of digits on one hand or foot. The Mayans used counters, pebbles, to represent their units and a short sick or a bean pod to represent the fives.

__The Egyptians __

The Egyptians number system was found on walls, poems, stones, and monument walls of ancient times. The Egyptians used animals to help them count. The Egyptians used whole numbers to 1, 000,000. There was always a sign for every power of ten such as for I there was a vertical line and for 10 there was there was a sign with the shape of a u; for a 100 there was a spiral rope, for 1000 there was a lotus blossom and for 10,000 there was a raised finger but it was a little bit bent. 100,000 it was a tadpole and for 1,000,000 it was a kneeling genie with upraised arms. That was what number system that helped the Egyptians and that was what they used. __Analysis __

I found out what the ancients used for their number system such as they used an abacus, animals, sticks, some body parts or drawings to help them count. I also found out how a part of their number system looked like and how they used their number system such as the Egyptians preferred to count in 1,000s and for all those numbers they had a sign. __The Task Brief__
 * **I’m going to design and make a PowerPoint presentation describing the number zero and explaining its history. **

__The design specification __
 * It will have 8 pages
 * It will have a few visuals
 * It will have a common colored screen
 * Each page will have a heading

=**__Design__**=

__My Design__


 * Introduction about what the whole PowerPoint is about
 * What I have learnt about the number zero and what I have also learnt throughout the whole PowerPoint
 * Why do we use the number zero?
 * When, where and who spread the number zero all the way to Europe.
 * The Expansion of math’s
 * Bibliography
 * Concluding summary

I decided to change my question “how did the number zero spread all the way to Europe” because I had a more appropriate answer to the question “when, where and who spread the number zero all the way to Europe.

__My Plan __ In unit 5 we have been focusing on the number zero and have gone through the stages of Investigate, Plan, create, and evaluate. So far I am working on my plan to help with my next stage create.

The Resources I will need to be using: Internet, a computer, different resources, and PowerPoint.

 * It will have 8 pages
 * <span style="font-family: "Cambria","serif"; font-size: 19px;">It will have a few visuals
 * <span style="font-family: "Cambria","serif"; font-size: 19px;">It will have a common colored screen
 * <span style="font-family: "Cambria","serif"; font-size: 19px;">Each page will have a heading

<span style="font-family: "Arial","sans-serif"; font-size: 24px;">These are the four things I tried to include in my PowerPoint. In my PowerPoint I did have exactly eight pages that included
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">the first page was all about what the name of the whole slide was about
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">the second slide was the introduction and that was talking about what was included in my PowerPoint
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">the third slide was the two historical facts about the number zero
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">the fourth slide was talking about why we use the number zero and how it’s so important
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">The fifth slide was all about who, where and when did zero spread to Europe
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">The sixth slide was all about how zero expanded maths and the expansion of maths
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">The seventh slide was all about where I got all my resources from and information
 * <span style="font-family: "Arial","sans-serif"; font-size: 24px;">My eighth slide was all about what I have learnt about the number zero and I really enjoyed learning about how zero expanded maths

<span style="font-family: "Arial","sans-serif"; font-size: 24px;">I had exactly five pictures in my PowerPoint and in all my eight slides I had a coloured common screened background. In each slide it had a heading. I believe I did very well because I got all the things that I wanted to have on my PowerPoint correct.
