A brief history of numerical systems - Alessandra King

View full lesson: ed.ted.com/lessons/a-brief-his...
1, 2, 3, 4, 5, 6, 7, 8, 9... and 0. With just these ten symbols, we can write any rational number imaginable. But why these particular symbols? Why ten of them? And why do we arrange them the way we do? Alessandra King gives a brief history of numerical systems.

Zero was first used in India by Indians as a NUMBER and hence India is generally given the credit for Zero. Mayans, Babylonians and most likely Indians as well used it earlier, but only as a placeholder and not a number. It was Brahmagupta who elevated zero to the status of a number and formally stated mathematical rules to use it as a number. Aryabhatta also may have been aware of zero as a number but all of his original work has been lost. Why is it Called the Indian-Arabic Numeral System? Fibonacci called this system the “the Modus Indorum” or “method of the Indians” (the Brahmi and Hindu) and introduced it in his masterwork Liber Abaci (1202). Fibonacci calls the Indian-Arabic numeral system “the method of the Indians” because the system originated in India. It was then brought to the middle-east by Muhammad ibn Musa al-Khwarizmi. Thus today we call it the Indian-Arabic system after the two cultures who developed the system before us. The omission and whitewashing of Brahmagupta and India's contribution to the numerical system seems to be a very deliberate act. Observe how facts of zero's use as a number is deliberately misrepresented and misguided and falsely attributed to the Mayans and other cultures. Mayans and other older cultures used it as a placeholder and not a number. At the end of the day this is merely pop culture and all the misrepresentations stated here in wonderful graphics becomes the truth. Nobody would care for scholarly articles such as Liber Abaci by Fibonacci.

[@chrisg3030]

Why ten? People usually assume it's because we have ten fingers, which makes sense. But I see something about the arithmetic of number ten itself which makes it practical for use in positional notation. Draw a cross hair grid like a big + sign. Put a pebble in say the top right quadrant to represent 1. Move it to the next quadrant position clockwise, the bottom right, that represents 2. Bottom left for 3, top left for 4. Keep it there but now add another pebble in the top right, so now you have a representation for 4 + 1, or 5. To cut a long story short, once all four quadrants are each occupied by one pebble (or pencil mark if you like) using this rule you have a representation for ten, based on the fact that 1+2+3+4=10. Of course you could achieve the same thing with a grid with, say, just three spaces, like a Mercedes star, which means using the base 6, or maybe one with 5 spaces for base 15. Evidence for the 4-space cross hair grid origin could be the form of the addition sign, +, we use (yes, I know there are other explanations for that). And that if fingers still have to be involved, there are 4 distinct spaces between each finger on one hand - or handprint - to place your pebbles or marks.

I always wondered what would happen if we had come up with an extra number. Would some calculations change/loose meaning?

[@miguelconfesor4701]

it would definitely change. try considering bases other than 10 and you will see the big difference

[@sharonjuniorchess]

You already use another system based on 60 to count time and in the UK not so long ago they used to count money as 12 pennies to a shilling and 20 shillings to a pound. Instead of 100 pennies to a pound(working in base 10). If you want to represent the number 11 & 12 in a single character positional notation (as suggested in your comment) you just invent a character to represent the two extra numbers required for 10 & 11 (say 10=@ and 11=#) but now you are counting in base 12 instead of base 10. So # + 1 = 10 (base 12).

[@Kreze202]

It wouldn't lose it's meaning, but it would change slightly. For example in a hexadecimal operation, we can calculate A (which is 10 in decimals)+ 8 and get 12, although 12 in hexadecimal still represents 18 in decimal.

I'm a supporter of base 12! Who else watches Numberphile?!

[@MrDiarukia]

I watch Numberphile. But I think base 12 might be too cumbersome to implement. We would have to implement two new symbols for everything. And another problem are measurements, while the metric system is wonderful for base 10, the current imperial system is annoying even in base 12 as it is not in 12^n steps but sometimes 4 or 12 or 60 and so on...

[@florianju5638]

I watch Numberphile aswell (like it very much!), but I dont like a Base 12 System.

[@nosuchthing8]

Blan Morrison I support base 10 for the same reason tau versus pi. If one method is easier to teach to children, you choose that method. Having ten fingers makes it easier to teach to a child. same as tau. We want math accessable.

[@florianju5638]

nosuchthing8 that is a really good point!

[@MultiWilliam15]

As much as I want to count in base 12, it's just hard to shift. I don't know, maybe because of the notation. Suppose the counting system is (0) 1 2 3 4 5 6 7 8 9 10 X Y where X=11 and Y=12, I would just think of 11 and 12 instead of X and Y, which defeats the purpose of base 12. Basically, it's hardwired into my brain.

[@lumri2002]

According to our college professor the decimal number system was based in Hindu-Arabic number system where basic digits of counting use 1, 2, 3, 4, 5, 6, 7, 8, 9 that were adapted by Arabs from Indians, but the Arabs also added the 0 to the number system. I don't know how accurate such information, we may then investigate if we want to. Perhaps zero may have just been a concept by the Indians in philosophy during ancient times, but the Arabs who may have learned from Al-Kwarizmi then used it early as numeral. On the other hand the ancient Mayan civilization in South America separately developed vigesimal number system which included zero numeral.

[@user-uj2tk2tv3z]

Zero was invented by Indian

[@Edit-nk6nb]

Question: While our modern day Arabic alphabet spread from the North African Maghreb region, why was that used over Latin or perhaps Greek ? Perhaps due to only certain members of the church were allowed to learn Latin, or was it something else ?

[@ikartikthakur]

. Yeah yeah!.. what less could you expect from first civilization!

[@Bleepbloopitty]

Thankyou fo rthe video :) But, Aryabhata was the one who invented the number 0 and Mayans had also used but the symbol was different and their number system was not exactly borrowed by the western civilisation. The number Zero which was invented by the HINDU INDIAN was Aryabhata. :) Have a nice day. Peace :)

[@Hal2718]

YuiHritsua The video wasn't claiming that the Maya* (Mayan is the adjective form) contributed to the zero we use today. It was simply another civilization that independently came up with the concept.

[@sagirahmed9309]

Beautiful animation and great info! Meanwhile in the comments, people are fighting over who invented what.

[@nessroque]

TedEd why are there a lot of plants in the animations? Just wondering. Thanks!

Wow look at how many illuminati signs are in this video

Hey please can you tell me the meaning of illuminati signs

[@zakuro8532]

A tetragon is not an illuminati sign. The illuminati sign is a tetragon.

[@SubstratumMaxima]

Indians not credited with zero?Indians also not credited for discovery of place value system? Indians just not perfected but also invented these systems on the first place!! in video it is said that mayans independantly pioneered concept of zero without mentioning any indian contribution. its not correct.

[@Hal2718]

Rohan Kokane The video did credit zero to the Indians. It's also not claiming that the Maya contributed to the zero we use today.

[@garrusn7702]

Rohan Kokane Mayans developed those things independently.

[@user-vo8zx1db6m]

They did credit India, they said India perfected the base 10 system, and said the Mayans also figured out 0, they just couldn't spread it because they were isolated from the rest of the world.

[@myxo9441]

im not sure about the ten fingers theory. i mean if that's the case then there should be 11 symbols. one more independent symbol for number 10 as zero isnt represented in a finger. why just 0 to 9? am i missing something or nah? any ideas?

[@jhewattimury]

is the value of the number always stays the same? if there is some other advance civilization out there, how can we know for sure that their value of constants like Pi can be same, false, or even more accurate than ours. based on their own numeric system and how they calculate must be different.

[@pez4]

This has to do with the "are mathematics invented or discovered" thing, the numeric system is a way to express values, for example pi as you said, but the thing with constants like pi is that they are defined by a natural phenomena, pi is the number of times that the diameter of a circle fits in its perimeter, no matter what numbers you use (or if you use them at all, the greeks found pi using geometry only) this value is the same. Pi in decimal is 3.141592... Pi in binary is 11.00100 10000... Pi in duodecimal is 3.18480... Pi in hexadecimal is 3.243F6... Even if they look different they all represent the same thing, and if an advance civilization out there studies circles, they are likely to find this value.

[@jhewattimury]

Have another question, by switching to other base system, there is no changes that we can calculate more accurate or even make it easy to calculate?

[@pez4]

Yes it does help and we actually do it all the time, for example: In calculus the logarithms are used in base "e" which is roughly 2.72 in decimal, this makes taking derivatives, anti-derivatives and integrals of exponential functions much easier and accurate. When analyzing trigonometric functions, we use the "pi" based angle measuring system of radians, which makes calculations less messier (and therefore, more accurate). And people who want to make the duodecimal system the default system for daily use argue that fractions are easier to work with in mental calculations, the best example of this is that the decimal one third is written as 0.333... whereas in duodecimal it becomes an easy to work with 0.4

[@jhewattimury]

Thank you. I need to learn more

[@user-vo8zx1db6m]

Watch Numberphiles video on it.

[@chan_for]

The number "0" or Hindu Numeric System has its roots much older than the accepted dates by scholars. While 6-8th century was the only time when Islamic-Arabic invasion began to rise in Indian land. Number 0 is used to describe creation-existence in Hindu spiritual texts, since space & creation is indivisible/infinite just like the number 0

actually the number zero was invented by Aryabhatta in India. I am not forcing you to agree with me but it's a fact that 0 was invented by Aryabhatta. i regret to say that ted ed has been a little biased in this video

[@user-vo8zx1db6m]

Both the Indians and Mayans invented 0. The Mayans couldn't spread it, they were isolated in South America. They credited India, saying that they perfected the base 10 system.

[@moreira999]

Wild Bore Central America or Mesoamerica, not South America.

[@NoorCrony]

Which software did they use to make such a beautiful animation? @TED-Ed

[@Jinks1447]

The invention of printing resulted in the standardized symbols we use today. In particular 5 closely resembled an "open" 4 but 5's shape was altered to the "hook" shaped symbol of the present. 7 was also an upside-down V shape but was changed, probably to avoid confusion with a V or capital A.

@youtubehero FYI indians invented flush toilet. So next time you poop remember this!!!

[@aryansaxena03]

KZbin Hero Your mom poops on streets

[@BreakFix]

Apoorv Tyagi The numerical system was invented by Arabs, not by Indians. The reason the video mention "Arab-Indian" was because arabs conquered India and lived there. The system came from Arabs. Not from the Hindus or the English. No way I will stand aside and let you take credit for something you didn't do,

[@soumik7.b]

BreakFix The number 0 was infected by Aryabhatta,go Google it.. Do you have any article/journals to prove what you are stating? Or are you just blabbering¿
