For all the math people on this site, beware, you may be suspected of terrorism.

Your language (mathematics) has long seemed to look like Greek (or Arabic) to me.

It's worse than you suspect. "Algebra" is an Arabic word!!!! Tens of millions of high schoolers are being corrupted by that filthy Muslim mathematical ideology. Thank God that when Trump is in charge, he'll ban the teaching of algebra. In fact, he may ban the teaching of addition and subtraction, as those things are used to calculate poll numbers.

Actually, aren't our numbers system Indio-Arabic? So, technically, math is Arabic and linked to terrorism.

The thing about the article that really annoys me is no one questioned why writing in Arabic is evidence of terrorism. The language of Arabic is by itself just a language and there are millions of people who read and write it including the guys at my local bodega.

We are in some sad times when writing in Arabic may have you questioned now by the authorities and taken off a plane.

I don't know the complete answer. What I can offer is this: The system of numerals most of us in the U.S. use are generally called Arabic numerals here. I asked a colleague from Egypt why they didn't use Arabic numerals. He said the numerals they used are Indian numerals. Arabic and Indian (or Arabic-Indic) numerals are shown as the first two lines of the image here.

Math would be very difficult without expression in Arabic numerals. Can anyone convert an Arabic numeral "2016" into a Roman numeral?

I believe the lady mentioned in the article is a Trumper and she was on her way to a Trump rally. The only thing I consider positive from the article is that she missed a Trump rally due to her own ignorance and stupidity.

I'm sure many here can:

MMXVI

Actually, since we clicked over to the new millennium, the years have become much simpler to write out in Roman numerals. But I take your point. Try to divide MMXVI by XLVIII without converting to another numeric representation (or using your abacus! :P), right?

XLII


By the way, has the naming of Superbowls now gone permanently to Arabic numerals, or was "50" a one-time deviation?

Thanks for that graphic Doc. I always wondered if numbers were universal and now I know they are not.

It's a great day when you can learn something new on a forum :)

I think it is interesting that from all the diverse cultures, customs, alphabets, etc., all (or at least almost all) numeral systems have evolved as base 10. Probably has something to do with the number of fingers humans have. I understand benefits of binary and even octal systems for machines, but the Roman numeral system seems unnecessarily complex. How did they ever have successful commerce?

Roman numerals are actually base 5 instead of ten and yes that probably comes down to five fingers on humans as well

Looks like back to Roman numerals this year. I'm guessing the deviation was because "Super Bowl L" just didn't sound momentous enough for the anniversary.

I don't think so -- more like semi-decimal or something. There is no distinct representation for 25 or 125 or 625 to distinguish it from the decimal system.

That's surprising. "SUPERBOWL XLIX" (49) is fine, but "SUPERBOWL L" just looks like a typo, or someone speaking with a drawl, so I understand going to Arabic digits. But the same will be true for the next three years: "SUPERBOWL LI" looks somewhat like a word, and so does "SUPERBOWL LII" and "SUPERBOWL LIII".

Are you going to "superbowlie"?

And in four years, will we have SUPERBOWL LIV? Will Aerosmith play the halftime show?

Yes, darkoz, I understood your intent. Roman numerals are not base 5, in the same sense as our base 10 or binary systems. They are perhaps more related to the Tally mark system of counting, with 5 being a common change point in the tally.

I looked at that Wiki page on tally marks and found a couple of things that interested me. The dot-and-line tally mark system, said to be in common use in forestry, looks more useful than the four plus a diagonal that I learned long ago. The dot-and-line even counts well to 10. Wish I had learned that one as a child instead.

I also liked the one said to be common in cultures using the Chinese character set, with the 正 character used for tallying to 5. Maybe we need member NokTang to educate us on this. And I guess Hullabaloo was right about the new things you can learn on a forum (plus where you wander from there).

50 was a one time deviation. They'll probably do it for 100 as well. I won't be in Vegas for Super Bowl LI this season. Lol
