i heard he'll teach kids the "latin" alphabet instead of Amerian one😡

I dont understand this. When I was in Palestine, they definitely used different numerals.

Like, I guess they invented base 10? Or math? But the characters they use for numbers are absolutely different

If you look at the Hindu-Arabic numerals first used in Europe in the middle ages, they looked very much like modern numerals used in Arabic. This is the modern set:

١٢٣٤٥٦٧٨٩٠

Some of those will look more familiar if you rotate them 90 degrees CCW.

Basically, what we call "Arabic Numerals", including the number 0, have their origin in India. Europe got them from Arabic scholars, and therefore called them "Arabic".

The main factor is the decimal system of writing and having the concept of a zero in contrast to the odd, additive and subtractive writing of the Roman numerals, which didn't even know a 0, and made multiplication a pain and division nearly impossible.

What glyph is actually used for a one, be it a 1 or a ١, is absolutely secondary.

I want to correct something. They knew what nothing meant. They just didn't conceptualize the absence of things as a number. And honestly, it's a bit weird, but it is useful. You can't have 0 apples, but the concept is useful for math.

[–] sem@piefed.blahaj.zone 9 points 4 days ago (1 children)

I have 0 apples right now, and most of the time!

[–] Cethin@lemmy.zip 5 points 4 days ago (1 children)

Arguably, sure. The way they'd understand it is you don't have apples though, not that you have zero. With our understanding, it makes some sense, but I'd say even today that's odd to say. It isn't wrong, but it is strange to say you posses everything in the universe (and anything else too), just in quantities of zero. It makes more sense to say you don't possess them.

[–] sem@piefed.blahaj.zone 4 points 4 days ago* (last edited 4 days ago)

It definitely makes sense in the same way that the famous experiment on abstract thought makes sense. Iirc, The experimenter a hundred years ago or more asked various people in different parts of Germany questions like, if a bird flies 20 miles an hour, about how long would it take to fly from Berlin to Frankfurt, and most people just couldn't entertain the question and would say that makes no sense a bird would never fly between those places.

It's only with our education system today that more people could entertain the question, how long a bird would take to fly from Frankfurt to Berlin, even if no real bird would ever do it, or not bat an eye at possessing everything in the universe in quantities of zero.

Of course they knew what nothing meant. They even had a word for it: nullum. Sounds familiar, somehow. But the key is to apply this to math, and having an actual symbol for it.

I think your confusion is the other side of what the article was discussing.

The problem is, there have been a lot of number systems in the past. The one we currently use is based on the Arabic system. In common usage you would simply call them numbers. But in a technical sense, to distinguish from other numbering systems past and present, they're also called Arabic Numerals because that's their origin.

Clearly this ignores the fact Arabic is still around and using real Arabic numbers and that is both confusing and maybe problematic. But I think the technical reason it sticks around is to acknowledge their source and have a more specific term when there is a need

While the origin of Arabic numerals is actually Indian.

[–] XeroxCool@lemmy.world 12 points 5 days ago (1 children)

Looking at Wikipedia, we're talking about western Arabic numerals in Europe/USA (TIL). Did you use one of the versions listed here as Eastern arabic numerals? Briefly reading the history, eastern is more common across modern Arabic regions.

If they force Arabic numerals and the Latin alphabet on our children, I’m leaving!
