What's "cool" about the number 1337? (the number, not the dialect)?
90213
it isn't prime: it's divisible by 7 (which is one of my favourite numbers).\nIf you add it to 668^2 you get 669^2 (but that's a trick you can do with every odd number).

If I recall, it's something along the lines of ALT + 3. It's a single number, lower digits. I'm on a laptop, so I can't test it.

uh...7? my favorite number. hehe.

It's unknown! Here's a couple links if you haven't looked at them already.\n\nhttp://mathworld.wolfram.com/OddPerfectNumber.html\n\nhttp://en.wikipedia.org/wiki/Perfect_number#Odd_perfect_numbers

Numbers 1 - 9 are spelled out, once you get to10 and above, you can just use the numerals. Here's a web site to prove my point...\n\nhttp://www.grammarbook.com/numbers/numbers.asp

I know what you mean.\n\nThe letter 'A' is not in the spelling of the numbers 1 - 100. \n\n\n\n--- LeeeN

Well, why is the number 18 in Latin pronounced duodeviginti (2 down from 20), instead of octodecim (following the pattern of the numbers from 11-17)? Same goes for Spanish, but with different wording.\n\nAlso, then why in Chinese do we not say one ten (and) three for 13 instead of ten (and) three, but we say one hundred one ten three for 113? (translated for your benefit)\n\nThere's just something in the etymology of the numbers that dictate it that way. (The others have the explanations of the specific etymology of the number 11)

111221, 312211, 13112221, 1113213211, ...\nOR\n1231, 131221, 132231, 232221, 134211, ...\nOR\n3112, 211213, 312213, 212223, 114213, ...\n\nEach is based on the digit makeup of the previous term, but I need one more term in the sequence to be sure of the rule.

"triangular numbers" they're called

It's so that the person you are talking to knows what you are talking about.\n\nWhat would the alternative be? "Twelve and seven hundred and eighty-nine thousandths?" That's a bit cumbersome.\n\nThe decimal point *creates* a division between the numbers, so we need to replicate that division by saying "point." It just makes sense.

It could be that they are giving a number to mean a long amount of time. It could be that a year was measured differently in his time. It could be a translation issue. Maybe the world they are translating is supposed to be month and not year. If so, if he lived 950 years, it would actually be just over 79 years.

I do both of those and I also test numbers for divisibility.  My car license plate has as its numeric part the number 594 which is divisible by 11, that's how I remember my license plate number.  Also, when someone asks me to pick a number between 1 and 10, I usually pick pi, phi, or e, just to be a smart@$$.  They didn't say an INTEGER between 1 and 10, did they???

congrats, but that is such a weird date to be born on... i've heard that there is no significance to those numbers, but still... a little weird.

It would be cool if it were still there\n\n6.022*10^-23\nHow the fuck do I still remember that number?
