250 written properly in Arabic numbers. 20-30 years ago we called our numbers Arabic numbers, but Arabic cultures do not use our call our modern numbers Arabic. They have their own Arabic-Arabic numbers.
This is something of a Mandela Effect, whereby people have been educated and are calling our numbers India Numbers, but still in India they use different numbers. So our Arabic-India Numbers are made up numbers based upon what they used in India.
But right now in the USA Indians from Asia and Indians native to America are NOT YET sorted out. Yet it has been sorted in the UK and Canada.
The best way to fix this situation is to refer to anything of from India of the Old World/Asia, should be kept in the "Singular Asian Sense." Asians often have singular plural/issues with English nouns. Many Asian languages don't have the plural form, for nous. We can meet Asia half way by using "India" like an Asian noun.
Example: " I like India food, they are India people, You are India-American, That is great India song, That neighborhood is full on India people." Thus is fun to think like the Asian in the singular sense of nouns, since many nouns don't have a plural form. And if you ever say Indian, it will refer to Native Americans.
Anyways, if you are Arab-American, enjoy this flag for the 250th USA birthday with this Arabic-Arabic numbered flag.
