The History of Arabic Numerals

PATREON: / generalistpapers
The so called Arabic numbers are everywhere in our lives. So much so that I bet you haven’t thought much about them. Where did they come from? Well, in this video we'll track their evolution through time AND space, so strap in.

Hindu Arabic Numerals are actually Indian Numerals because Arabic script is from Right to left but Brahmi script is from Left to right from which Hindu Arabic numerals originated.

[@Cau_No]

Have you ever noticed that numbers, when getting bigger, grow on their *left* side? That's because we kept the writing order from Arabic when they entered into Europe. We are basically reading them backwards. In Hebrew and Arabic texts the numbers look exactly the same as in the translated text with numerals. And as the video stated, 'Modern Arabic' numerals look neither like the original hindu nor arabic.

[@WilfChadwick]

@@Cau_No "reading them backwards"?! Luckily, in English, we use the most logical way of verbalising the written numbers. Imagine reading and saying them "backwards", we might end up calling 'everyone not islamic must be murdered', 'peaceful'.

[@Cau_No]

@@WilfChadwick Luckily, I'm not English. Maybe you want to redact your thoughts into clear text, then I might be able to understand what you are talking about. And when you begin verbalising the number from the left, then you start at its highest digit - which is, as I explained, at its end.

[@WilfChadwick]

@@Cau_No Please don't start a sentence with "And", it makes you appear somewhat stupid. Luckily, i am English. 23 - Twenty (first written and said), three (second written and said). - Drie (tweede geschreven eerst gesproken), en twintig (eerst geschreven tweede gesproken). Arabic is the same as, eg Dutch above, except for the weird 200's anomaly. Which is read backwards? Ps. 13-14-15-16-17-18-19 in English. Backwards?

[@Cau_No]

@@WilfChadwick Yeah, attack the form first before you try to argue the content - really bad style. I am talking about the digits, not the words! You have to align numbers on their right side to sum them up, that's contrary to written text. That's what 'backwards' meant. The names of the numbers were not the point. But to take your example - "drie en twintig en honderd" would for this case be the logical name for 123, as when adding you begin *at the numbers' end*. But we don't do that anywhere in Europe. And I don't give a **** what you think about my English.

[@mahmoudbenchehida9315]

Before the decimal system numerals, Arabs did have a writing system for numbers. They used letters to represent numbers. Aleph represented 1, Ba represented 2, Gim represented 3, Dal represented 4, Ya represented 10, Kaph represented 20 and so on. Similar system was used in Greek and Hebrew. Saying they just used fingers is just gross.

[@cjsm1006]

Yes, considering the abacus was invented, oh, a mere 4000 years, and was known to the ancient Sumerians, Egyptians, Greeks and Romans, I was actually slightly shocked when he dismissed the ancients as ignorant finger counters. Add in the fact that the ancient Greeks, Hebrews and Arabs had a number system, which though not modern, was far superior to the insane Roman Numeral system. That is, in ancient Greek, for example, the number 847 is written as 3 numbers from the letters for 800, 40, and 7. So it would parallel Arabic numbers in appearance and meaning. That is, in both the Arabic and Greek version of 847, the first number means 800, the second number 40, and the last number means 7, and is written as a 3 digit number.

As an Indian and even someone who learns right, never understood this obsession claiming Indian things are scientific. It's a catch-all phrase that can mean well structured, has an internal logic, cause-effect dynamic etc. The single worst disservice you can do to Indian culture and history is give such wide undefined adjectives and FAIL at demonstrating your own description. All I need to do is to pull up the definition of scientific and ask you to demonstrate a scientific principle. Then these replies follow "That is a linguistic feature, not science" "every language has evolved to reflect it's environment and culture" "high culture has always been self referential, nothing new".

[@nixonxc7157]

@@salim_Salim... The concept of zero is believed to have originated in the Hindu cultural and spiritual space around the 5th century CE. The first recorded zero appeared in Mesopotamia around 3 B.C., and the Mayans invented it independently circa 4 A.D.. In the 7th century, Brahmagupta, a Hindu astronomer and mathematician, developed the earliest known methods for using zero within calculations. He used small dots under numbers to show a zero placeholder, and he was the first to show that subtracting a number from itself results in zero. The word for zero in Sanskrit is śūnya, which refers to nothingness. Brahmagupta and others viewed the zero as having a null value, called “sunya”. The discovery of zero would later change the way civilizations developed. With modern finance, it is much easier to conceptualize trade and business.

I was taught at a very young age that the Arabic numerals we use had a basic meaning from the original meaning of the symbol it was derived from; 2 meant a woman with child, 8 was two bags of gold. I do not remember what the others started out as and that is what I have trying to find to no success.

[@keesdevos4816]

My guess is that one aspect of history should be added. Meaning to say that women who did most of actual arithmatic in bartering probably "invented" the small zero being their help in decimising using rings on their pinks. Being the reason for purposely not continuing with eleven, twelve etc. If writers\mathematitians had really "invented" cyphering they would have likely expanded their coding if even to impress their system. The overall importance of decimising withheld this?

What if I told you that Arabic numerals are written incorrectly? there are no curves in Arabic numerals, but rather angles number zero has no angle number one has one angle two has two angles and so on until the number nine this is how Al-Khwarizmi wrote it

[@abunafeesmuhammad8464]

Some contradictory and confusing narratives are here. Arab mathematician, Alkhawarjmi was the man who derived the symbol of Arabic numerals based on number of angels, like

Al Khwarizmi was not Arab but belonged to Khwarizm which is in Central Asia close to Afghanistan. Khwarizmi himself noted in the title of his book itself that the numbers were of Indian origin.

Merchants of the North Mediterranian allways had contact to merchants of the South Mediterranian. The Arabic Numbers arrived in the South and very soon they were in the North. You mention Spanish monks and Pope Sylvester important for the transport. That means, what is written, did exist. What is not written, did not exist. Are you sure? A cheap medium was necessary to spread letters and numbers. This was paper, invented by the Chinese. You can develope a more plausible theory about spreading numbers and letters if you look at the procedure of writing. This all is a combination of head and hand.

Hindu Arabic Numerals are actually Indian Numerals because Arabic script is from Right to left but Brahmi script is from Left to right from which Hindu Arabic numerals originated.

Well, that was interesting. I had always thought that the numbers we use today were based on angles. Each number from 1 to 9 can be written with the equivalent number of angles if the "curves" are straightened. The easy one, No. 3, has 3 angles. Try it and see what I mean.

[@eruben2]

How does 9 straightened out have 9 angles?

@@eruben2 A stroke through the leg of the 9.

[@eruben2]

@@irene3196 I just don’t see it. The early numbers, maybe, but how does a 7 have 7 angles? Adding a stroke through the leg of the 9 still doesn’t make 9 angles?

[@irene3196]

@@eruben2 For the 9 ... 4 angles in the squared off top, 4 angles formed with a stroke through the leg of the 9, 1 angle where the leg joins the top square, total 9 angles. For the 7 ... 1 angle where the leg joins the top, 4 angles where a stroke is through the leg, and a stroke at the left end of the top of the 7 gives 2 angles.
