### The Need of Numbers (12 January 2010)

As an individual, consider

1) Why is there a need of having numbers?

2) When did the first use of numbers, based on your imagination, occur?

Post your response under the Comment section.

1. I think that there is a need of numbers because it helps man-kind to interact.

I think that the first use of numbers occur during 3000BC, by the Paleolithic.

2. We need numbers to help us count currency and things like animals or fruits. Without numbers, the world would be in chaos because there will be no currency and people will be quarreling about who owes who what. The first use of numbers, to me, is during Egyptian times, where Egyptian numerals where used for the first time.

3. We need numbers so we can organise stuff better and we can communicate with one another much much more easier.

I think that the first use of numbers occured when people were trying to communicate amount of an item, but didn't know how to explain, so hence, they created numbers.

4. We need numbers to count items such as currency etc. without having to bring all of the item you want to count and show them to the person.

I think that the first use of numbers occured when people were trading their items for another person's items, such as 10 sacks of rice for 15 sacks of barly

5. I think we need numbers as it helps us communicate with each other easily when trading. It also helps us count easily.
I think numbers originated when people started trading things with each other but had a difficulty counting and communicating so they invented numbers

6. We need numbers to make our life so much easier esp. when we are counting, buying things, etc, etc. Having numbers (referring to only just the modern Arabic number system) is good also because the people all around the world (everyone) know the same set of numbers so when we have a need like explain to other people (not singaporeans) about some financial crisis or problems which involves numbers, they would know those numbers, not like in the past where different countries have different number systems.
If you are referring to using tally marks to replace numbers in the past, I think that the first use of numbers dates back to around 30000 BC, used by Paleolithic peoples. But if you are referring to the counting system, I think it was actually invented in India, then borrowed and popularised by the Arabs, which we have now, the "Arabic" system.

7. (1) I think that we need numbers to help us count and it also makes it easier for us to communicate and organise things.
(2) I think the first use of numbers occurred when people needed to trade things with each other and count money and things, so they invented numbers.

8. 1) I think there a need of having numbers because it helps us count and we won't be confused with the numbers. It also helps us to communicate with others better and organize things properly and neatly.
2) I think the first use of numbers was when some traders or merchants were trading things or selling their items but they found it quite difficult so that's how they invent numbers.

9. i think that numbers are needed to help us count easily. Like the example mr ng showed in class, if someone has a 100 things to trade, he has to make 100 knots.

i think the first use of numbers occur when people are trading in big amounts and need numbers for that use.

10. I think we need numbers to be able to count and to make life easier by being able to count big numbers.
I think it started when people found out that they had to compute and record numbers, and memory wasn't enough.

11. I think numbers are needed as without them, our world not be the same as today
I think it was when the people at that time found out that without numbers, it would be almost impossible to multiply big numbers.

12. 1) Why is there a need of having numbers?
We need numbers to help us count easier, so that we do not need to "tie knots".

2) When did the first use of numbers, based on your imagination, occur?
I think the first use of numbers started when they started trading with each other.

13. We need numbers as it is very important in our daily lives. For example, if I need to remember that I have 100 photographs, I could just write it down using numbers but if there were no numbers, I cannot remember that at all.
I think when people started counting animals at 30 000B.C.

14. I think that numbers are important as it is easier to count.

I think numbers were first used in the egyptian civilization.

15. I think we need numbers as they help us as a symbol of quantity , to avoid misunderstandings and to help us count.

I think it appeared since the dawn of mankind.

16. We need numbers as we need to keep track of the quantity of things
I think it started as early as 3000bc

17. I think we need numbers as it can help us count more easily and more approximate.

I think numbers started out a very, very long time ago, maybe during the age of when the cavemen started
