I have never come across "X" as a hexadecimal notation for ten. As there is no equivalent for eleven, I am removing the "X". Should this be wrong, could whoever puts it back again please explain in what context "X" is used please. -- SGBailey 13:34, 2004 Mar 17 (UTC)

I notice that Number 10 redirects here. I suspect that this may be part of a standard for [[Number n]] to redirect to [[n (number)]], but given that it's a common short form of "Number 10 Downing Street", shouldn't it redirect to 10 Downing Street instead? I've just fixed the only two links to Number 10, which were references to 10 Downing Street, and I think it's much more likely that editors will use Number 10 to mean the house (or rather the British PM's office) than the number. Would anyone object to this change? --rbrwr± 17:13, 22 May 2005 (UTC)

Yes, I would object. I see your point, but it must be solved by some sort of disambiguation. Either, "Number 10" should be a disambiguation page linking to "10 (numer)" and "Number 10 Downing Street", or "Number 10" should redirect to a new page, "10 (disambiguation)", with those two links.--Niels Ø 19:27, May 23, 2005 (UTC)

Need a reference but no idea where to put it...[edit]

10 is 2 written in binary.

13 is not a semi-prime[edit]

In the "In Mathematics" section, this claim is made:

Ten is the smallest semiprime that is the sum of all the distinct prime numbers from its lower factor through its higher factor (10 = 2 + 3 + 5 = 2 . 5) Only three other small semiprimes (13, 39, and 371) share this attribute.

However, 13 is not a semi-prime number and cannot be described as the sum of all the distinct prime numbers from its lower factor through its higher factor. In fact, the only semiprimes from 4 to 62,710,561 are 10, 39, 155, and 371. --108.47.0.42 (talk) 22:11, 14 February 2014 (UTC)
