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

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.

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.

Arabic Numerals is ambiguous. We don't use eastern Arabic numerals in our schools.

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.
