Fun fact, the only numbers you can have in the denominator of a fraction where the resulting decimal doesn’t repeat infinitely are any multiples of the prime factors of your number systems base. So for base 10, the only fractions that won’t infinitely repeat as decimals are 1/(2^x*5^y), since the prime factors of 10 are 2 and 5
I still remember when I joked with a cashier at my college that I’ve used Arabic numerals my whole life, but still confuse them, and she was impressed that I knew Arabic numerals because she didn’t know it was the 0-9 symbols we all know and love. I laugh about that moment to this day.
Yes. I've heard this method called the Russian peasants' method (or similar names). I didn't know Romans used it too. I'd like to point out that halving say LVI (getting XXVIII) is not trivial.
This algorithm has the advantage of not requiring the memorization of multiplication tables. You only ever halve or double numbers. You don't need to know what e.g. 8*7 or 6*4 are. Hence why it is called peasants' multiplication. But it was used long before that, probably invented by the ancient Egyptians.
while this is clearly a meme, let me try to give an overly serious answer: our number system is nice in that it makes arithmetic of large numbers into something you can break up into smaller ones. Like splitting up addition and multiplication by digits. The trick being that the way we write down numbers tells us what it's remainders for division by powers of 10 are. So in effect we just learn all the stuff up tp 10 by heart and then the notation tells us how a number is split up into 10s. This works really great for stuff like that, but operations like exponentiation gets very tedious. Like 13+13 is easy, 13*13 takes a couple seconds, but 13^13? Hard. Log_8(13)? No clue. One thing that can do better on those operations would be a notation that would tell you what the log (or even repeated logs) of a number is. Then 13*13 becomes as easy as addition is for us since log(13*13)=log(13)+log(13) and even better 13^13 would be easy as log(13^13)=13*log(13) which you could simplify just like the 13*13 example. Does such a number system exist? Well the closest thing in terms of written stuff I can think of would be the scientific notation. If you learn the log_10 of the integers from 1-10 (the way we currently learn stuff like 3+5=8) then then you can pretty easily see the log of a number when written like that. 500 would be written 5*10^2 if you know that log_10(5) is about 0.7 then you can immediately see that log_10(500) is about 2.7 telling you that the log(500^500)~1350 which means 500^500 is about 10^1350. Not super accurate (we're off by a factor of 3) but doing the calculation the decimal way would be very very tedious. Downside - addition isn't as easy. In the extreme case (just writing down the log of a number) addition becomes exactly as tedious as exponentiation is for arabic numerals. THE REAL DEAL: There is a real and actually useful implementation of logarithmic number representation though that was very popular last century and widely used. Depending on how old you are you, or your parents, might have learned how to use it in school. Slide rules. What the abacus (in one way of using it) is for arabic numberals te slide rule is for logarithmic numbers. A number is represented by a position of a slider (which is nicely marked with the arabic number, so you don't need to remember yourself) and magically even crazy difficult operations like 9.81*350*Log(890/757) or (6*10^11 * 6*10^24 / 6400)^0.5 become a trivial matter of sliding a plastic marker back and forth a couple of times. These incidentally are the calculations for the maximum speed an 890t fueled/757t empty spacecraft with an isp of 350s can achieve and the velocity required to escape the earths gravity - as you can see these are almost entirely exponentiation, multiplication and logs. Exactly the stuff a logarithmic number system works great for. It is no wonder you can see a lot of slide rules in footage taken at 60s nasa.
Yeah, it looks kind of like the Greek or Hebrew numeral system. Roman numerals are so much easier than those, it is the same difference as between Arabic and Roman.
Love these! You should do a follow up video on the Church's long resistance to the concept of zero which really delayed the adoption of Arabic numerals.
actually, people didn’t do maths with roman numerals, if you needed to add something, you needed the help of someone who knew how to use an abacus properly. that’s why fibonacci wrote “liber abaci” (the book of the abacus), in which he was against them.
Actually khawrazmi Iranian scientist redesigned those hindu numbers and from latin translation of his book these numbers spread in west . The numeral system came to be known to both the Persian mathematician Khwarizmi, who wrote a book, On the Calculation with Hindu Numerals in about 825, 830. Persian scientist Kushyar Gilani who wrote Kitab fi usul hisab al-hind (Principles of Hindu Reckoning) is one of the oldest surviving manuscripts using the Hindu numerals.[1

It took Japan until the 19th century to adopt them, but nowadays they are also common in everyday writing. They already used a decimal system adopted from China, which feels like it's somewhere between Arabic and Roman numerals. Even nowadays its quite intuitive to use since it got all ten decimal digits 0-9, it's just that powers of ten like 10 and 100 have their own characters so you write "ten-three" rather than "one-three" to say "thirteen". Meaning it was pretty easy to adapt for them. They still use their old numeral system as well in many places. No need to sweat about maybe 20 more characters if you already need to know like 3000.
The traditional Japanese / Chinese system is basically just writing it exactly as pronounced. Keep in mind that they don't have irregular numbers like eleven, twelve, the -teens and -ty's, instead they say ten-five for fifteen, two-ten for twenty etc, just like we say three-hundred or four-thousand. So instead of writing, for example, four-two-zero, they would write four-hundred-two-ten. And in fact, a system commonly used is actually combining Arabic and Chinese numerals. Whereas English spoken numerals are based on multiples of thousand, like thousand, million, billion, trillion etc, the Japanes numerals work in the same way but based on multiples of ten thousand: 万 man (ten thousand), 億 oku (100 million), 兆 chou (1 trillion) etc. Commonly, these are written with Chinese characters, while the rest of the number is written in Arabic numerals, so for example 420 million is ４億２０００万. You may even see something like 3.4万, meaning 34000, similar to how TH-cam uses 3.4K or 3.4M in English.
@@b4ttlemast0r??? There's a lot of irregular numerals in Japanese You even have to play with 2 sets of numbers while jumping from one another They're only kinda regular when removing all context (when you're not talking about quantities/counting anything/...) and even then there's usually a jump from Chinese to Japanese numerals for 4 and 7 in some cases and not others

A wonderful video that fulfills Horace's dictum of both delighting and instructing.

A deserved thumbs up! Love this channel!
2:28 Amazing! I saw this and was like "WTF, how does this even work", and then when trying it for myself with 32 in the left column, all of the sudden, it hit me: Dividing the left column in half until you get to 1 while doubling the other side basically means you are forcing the product of the 2 factors to be expressed by counting in binary!! I noticed it because cutting 32 in half gave me 16, 8, 4, 2, 1, which are all digit values used in binary. The number of times you can halve the left-side number gives you the number of binary digits you'll be adding together, and crossing out the even ones is like marking the digit "0" or "off". Then you add all the "1" or "on" bits together and get your number. You can kind of "binarize" any number in the left-hand though. That doesn't explain every tiny detail of it, but it gives me a pretty good idea of the basic mechanism and what's going on. :)
Thanks for the video. One fact about Roman numerals, worth of note, is about the number 4. You may know that the correct way to write down the number 4, is IV. But if you look at any clock face, you will find the writing IIII for the number 4. When written alone, the 4 is noted as IIII. That's why the Romans went to great lengths to avoid upsetting the father of all Gods, IVPITER. A stand alone 4 uses the same writing as the initials of the name IVPITER; and that would have attracted unnecessarily the attention of the capricious boss of all Gods. Therefore, the Romans avoided any occasion for even the slighter misunderstanding, so a standalone number 4 was written as IIII instead of IV. We can't say, even today, if the different notation for the number 4 was because of their extreme respect, or because of superstition...
I had once heard that the "IIII" on clock faces is used to make them seem more "balanced" because the numerals on the left side have more strokes. Interesting to see that there is an older explanation!

For example the Hungarian Kingdom used Arabic numerals since the middle of the 15th century. Anyways, good vid, thanks. :)

I quite wonder if that suited guy in the end is History Matter's OC -- I always see it in the videos when they reference certain historical technicalities.
The multiplication algorithm at 2:40 is just binary multiplication; dividing the first number and counting the odds decomposes the first number into binary (in the case of 13, 1101). The doubled multiples of the second number are just the number in binary with extra 0's on the end (1101, 11010, 110100, 1101000.) Though this algorithm was developed by the egyptians, it resembles the same algorithm used by computers to multiply. They may not have been writing out their numbers in binary, but this system of halving and doubling works because it implicitly invokes binary math.
13*13 = b1101*b1101 1101 (13) *1101 (13) = 1101 (13)+ 110100 (52)+ 1101000 (104) = 10101001 (169). The same numbers are summed as in the roman numeral example. 26 is not added, because in binary, the 2nd from the right digit is 0, just as the 2nd from the top row has an even in the left column.
I tend to call them Hindu-Arabic to give recognition to their actual inventors. In any case Hindu-Arabic numerals as used in Arabic speaking countries are different from but related to, the ones used in Europe.
You forgot to mention Algebra, Jabr Al Jabr, and how that superior math system can *only* work with Arabic Numerals and especially with the very special and non-intuitive number “0”. (The 0 number is what came from India/Pakistan specially, btw. :).

Fun fact, the only numbers you can have in the denominator of a fraction where the resulting decimal doesn’t repeat infinitely are any multiples of the prime factors of your number systems base. So for base 10, the only fractions that won’t infinitely repeat as decimals are 1/(2^x*5^y), since the prime factors of 10 are 2 and 5

The most interesting part of the video was seeing how multiplication with Roman numerals worked.
Yes. I've heard this method called the Russian peasants' method (or similar names). I didn't know Romans used it too. I'd like to point out that halving say LVI (getting XXVIII) is not trivial.
@@rosiefay7283 I'm still not over the part where 13/2=6
@@meberg500 idk if Roman numerals had a decimal back then, rounded up it'd be 6
This algorithm has the advantage of not requiring the memorization of multiplication tables. You only ever halve or double numbers. You don't need to know what e.g. 8*7 or 6*4 are. Hence why it is called peasants' multiplication. But it was used long before that, probably invented by the ancient Egyptians.
@@meberg500 You always round down / discard the remainder.
That is one of the most interesting things I’ve learnt in a long time… you rock ☺️
I wonder if there's a number system that has yet to be invented that would make Rocket Science easy for toddlers
while this is clearly a meme, let me try to give an overly serious answer:
our number system is nice in that it makes arithmetic of large numbers into something you can break up into smaller ones. Like splitting up addition and multiplication by digits. The trick being that the way we write down numbers tells us what it's remainders for division by powers of 10 are. So in effect we just learn all the stuff up tp 10 by heart and then the notation tells us how a number is split up into 10s. This works really great for stuff like that, but operations like exponentiation gets very tedious. Like 13+13 is easy, 13*13 takes a couple seconds, but 13^13? Hard. Log_8(13)? No clue.
One thing that can do better on those operations would be a notation that would tell you what the log (or even repeated logs) of a number is. Then 13*13 becomes as easy as addition is for us since log(13*13)=log(13)+log(13) and even better 13^13 would be easy as log(13^13)=13*log(13) which you could simplify just like the 13*13 example.
Does such a number system exist? Well the closest thing in terms of written stuff I can think of would be the scientific notation. If you learn the log_10 of the integers from 1-10 (the way we currently learn stuff like 3+5=8) then then you can pretty easily see the log of a number when written like that. 500 would be written 5*10^2 if you know that log_10(5) is about 0.7 then you can immediately see that log_10(500) is about 2.7 telling you that the log(500^500)~1350 which means 500^500 is about 10^1350. Not super accurate (we're off by a factor of 3) but doing the calculation the decimal way would be very very tedious.
Downside - addition isn't as easy. In the extreme case (just writing down the log of a number) addition becomes exactly as tedious as exponentiation is for arabic numerals.
THE REAL DEAL:
There is a real and actually useful implementation of logarithmic number representation though that was very popular last century and widely used. Depending on how old you are you, or your parents, might have learned how to use it in school. Slide rules. What the abacus (in one way of using it) is for arabic numberals te slide rule is for logarithmic numbers. A number is represented by a position of a slider (which is nicely marked with the arabic number, so you don't need to remember yourself) and magically even crazy difficult operations like 9.81*350*Log(890/757) or (6*10^11 * 6*10^24 / 6400)^0.5 become a trivial matter of sliding a plastic marker back and forth a couple of times. These incidentally are the calculations for the maximum speed an 890t fueled/757t empty spacecraft with an isp of 350s can achieve and the velocity required to escape the earths gravity - as you can see these are almost entirely exponentiation, multiplication and logs. Exactly the stuff a logarithmic number system works great for.
It is no wonder you can see a lot of slide rules in footage taken at 60s nasa.

It took Japan until the 19th century to adopt them, but nowadays they are also common in everyday writing.
They already used a decimal system adopted from China, which feels like it's somewhere between Arabic and Roman numerals. Even nowadays its quite intuitive to use since it got all ten decimal digits 0-9, it's just that powers of ten like 10 and 100 have their own characters so you write "ten-three" rather than "one-three" to say "thirteen". Meaning it was pretty easy to adapt for them.
They still use their old numeral system as well in many places. No need to sweat about maybe 20 more characters if you already need to know like 3000.
The traditional Japanese / Chinese system is basically just writing it exactly as pronounced. Keep in mind that they don't have irregular numbers like eleven, twelve, the -teens and -ty's, instead they say ten-five for fifteen, two-ten for twenty etc, just like we say three-hundred or four-thousand. So instead of writing, for example, four-two-zero, they would write four-hundred-two-ten. And in fact, a system commonly used is actually combining Arabic and Chinese numerals. Whereas English spoken numerals are based on multiples of thousand, like thousand, million, billion, trillion etc, the Japanes numerals work in the same way but based on multiples of ten thousand: 万 man (ten thousand), 億 oku (100 million), 兆 chou (1 trillion) etc. Commonly, these are written with Chinese characters, while the rest of the number is written in Arabic numerals, so for example 420 million is ４億２０００万. You may even see something like 3.4万, meaning 34000, similar to how TH-cam uses 3.4K or 3.4M in English.
@@b4ttlemast0r??? There's a lot of irregular numerals in Japanese
You even have to play with 2 sets of numbers while jumping from one another
They're only kinda regular when removing all context (when you're not talking about quantities/counting anything/...) and even then there's usually a jump from Chinese to Japanese numerals for 4 and 7 in some cases and not others

2:28 Amazing! I saw this and was like "WTF, how does this even work", and then when trying it for myself with 32 in the left column, all of the sudden, it hit me: Dividing the left column in half until you get to 1 while doubling the other side basically means you are forcing the product of the 2 factors to be expressed by counting in binary!! I noticed it because cutting 32 in half gave me 16, 8, 4, 2, 1, which are all digit values used in binary. The number of times you can halve the left-side number gives you the number of binary digits you'll be adding together, and crossing out the even ones is like marking the digit "0" or "off". Then you add all the "1" or "on" bits together and get your number. You can kind of "binarize" any number in the left-hand though. That doesn't explain every tiny detail of it, but it gives me a pretty good idea of the basic mechanism and what's going on. :)
So now does that mean that the Romans invented the binary numerical system when they learned to multiply?

One fact about Roman numerals, worth of note, is about the number 4.
You may know that the correct way to write down the number 4, is IV.
But if you look at any clock face, you will find the writing IIII for the number 4.
When written alone, the 4 is noted as IIII.
That's why the Romans went to great lengths to avoid upsetting the father of all Gods, IVPITER.
A stand alone 4 uses the same writing as the initials of the name IVPITER; and that would have attracted unnecessarily the attention of the capricious boss of all Gods.
Therefore, the Romans avoided any occasion for even the slighter misunderstanding, so a standalone number 4 was written as IIII instead of IV.
We can't say, even today, if the different notation for the number 4 was because of their extreme respect, or because of superstition...
Really? My kitchen clock had IIII rather than IV and I have always thought this was an error. Thanks for the enlightenment.
I had once heard that the "IIII" on clock faces is used to make them seem more "balanced" because the numerals on the left side have more strokes. Interesting to see that there is an older explanation!

The multiplication algorithm at 2:40 is just binary multiplication; dividing the first number and counting the odds decomposes the first number into binary (in the case of 13, 1101). The doubled multiples of the second number are just the number in binary with extra 0's on the end (1101, 11010, 110100, 1101000.) Though this algorithm was developed by the egyptians, it resembles the same algorithm used by computers to multiply. They may not have been writing out their numbers in binary, but this system of halving and doubling works because it implicitly invokes binary math.
13*13 = b1101*b1101
1101 (13)
*1101 (13)
=
1101 (13)+
110100 (52)+
1101000 (104)
=
10101001 (169).
The same numbers are summed as in the roman numeral example. 26 is not added, because in binary, the 2nd from the right digit is 0, just as the 2nd from the top row has an even in the left column.
I tend to call them Hindu-Arabic to give recognition to their actual inventors. In any case Hindu-Arabic numerals as used in Arabic speaking countries are different from but related to, the ones used in Europe.
Its ironic that the numerals used by the arabs are called indian numerals by them
@@partha1331It's also Ironic that Indian numbers are called Arabian numbers
@@trendshort_ Only idiots call it that.
Interesting, I never gave multiplication a thought using Roman numerals until this video. Great, info video!
Props for the papal crown 1:46
Just imagine how weird it would be to use imaginary and complex numbers with Roman Numerals.
Maths would be even worse
I think thats honestly the easiest implementation there is to be found. The notation remains very logical and easy.
You forgot to mention Algebra, Jabr Al Jabr, and how that superior math system can *only* work with Arabic Numerals and especially with the very special and non-intuitive number “0”. (The 0 number is what came from India/Pakistan specially, btw. :).
Though I am not sure if it was the Abbasid Mathematics that standardized the base-10 system we still use, or some other group from India/Pakistan.
@pulkit khanduri thats stupid, if their ancestors were hindu they can claim it as their heritage as india and pakistan never existed then, this is akin to saying hindus cannot claim mughal empire as their heritage or iranians cannot claim the sassanians as their heritage.
No we would just have used Greek letters
We would have used Greek letters
Aryabhatta was from today's India who invented 0 not Pakistan.
What I love about the Arabic Numberals is that it takes only one stroke of line with the exception of the number '4'
It makes it really fast to draw
*Hindu Arabic
Weirdly Indian invented all of these including 0 but they get no credit at all. Whole name is changed to "Arabic numerals" just because europeans got them from middle east
You can write 4 with one stroke if you do the closed top (similar to a triangle) version.
@@PK-se2jh Weirdly, the Arabs actually developed the system, made it proper, and used it for mathematics instead of just being a concept.
5 takes two strokes
