i think this should be moved to Multiplcation symbol Vincent.premysler 00:35, 6 August 2007 (UTC) vincent
well then this article should be moved to times sign and cross. dicklyon said so on is number sign ok Vincent.premysler 12:04, 6 August 2007 (UTC) vincent
but i think it would be hard to type it in with no redirect links and also i had a conflict with dicklyon about the title of number sign. i wanted to change the title of number sign to #. i dont like this. just move × to Notation for the cross product multiplication, and Cartesain product Vincent.premysler 15:51, 6 August 2007 (UTC) vincent

There are remarks about a similar glyph in Unicode for the vector or cross product, which say that this appears bigger than the normal times symbol. However, with the font my browser displays the page with, the vector product symbol is smaller than the times symbol. For comparison: U+00D7 = × (times), U+2A2F = ⨯ (vector product) I can't really confirm this now. If this can't be verified, should the size be mentioned at all? smiler ( talk) 14:35, 31 May 2008 (UTC)
I've never heard this called the "into" symbol. Can someone give a reference for this? -- Doradus ( talk) 20:37, 31 October 2010 (UTC)
In mathematics, "into" is used only for division, not for multiplication. Probably this confusion came from Latin language. In Latin, "in" is used for multiplication to read multiplication sign.
For example, "Clavis Mathematicae" written by William Oughtred in page 7 describes "4 in 6 fiet 24". http://books.google.co.jp/books?id=Ld5EAAAAcAAJ&printsec=frontcover&hl=ja&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false — Preceding unsigned comment added by Cozycube ( talk • contribs) 12:51, 29 February 2012 (UTC)
Isn't a dot (interpunct) also used as a multiplication sign? — Preceding unsigned comment added by 108.221.57.236 ( talk) 00:34, 29 April 2013 (UTC)
I was reviewing an article about a musician, and a table in the article included record sales. A few albums were noted as 2x platinum, a shorthand for "double platinum", meaning sales of 2 million units. I thought about changing it to 2× platinum and then decided I had no idea if convention made the 'x' more correct than '×'. Any one? jameslucas ( " " / +) 16:59, 23 April 2015 (UTC)
The article states that the multiplication symbol can be typed on a Mac using Shift+Option+. This just gives me a a breve (˘) (UK Keyboard, OS X 10.10.4). Does this key combination generate a × on any other keyboard? Or is it from a previous version of OS X? St3f ( talk) 07:49, 7 July 2015 (UTC)
I apologize for my lack of technical expertise, but how exactly do I type the multiplication symbol (×)? There's no "×" key on my keyboard, and while there are 254 alt codes (most of which are useless), none of them yield "×" (which would be useful). Go figure. :-\ So how do I type a "×" when I need it? (For this comment, I've been copying and pasting the "×" symbol from this article itself. But that's clumsy and shouldn't be necessary.) Captain Quirk ( talk) 17:47, 1 September 2016 (UTC)
ALT+0215 does it. There are a LOT more ALT-codes than just 254, although the "extra" ones may not be officially-recognized. My favorites are ALT+0151 and ALT+0153, for the grammatically-proper—though rarely-used—em-dash, and the Always Useful At Expressing Sarcasm™ trademark sign. ;) Sandwich ( talk) 20:21, 13 September 2017 (UTC)

In Unicode, multiplication sign, also known as the times sign or the dimension sign, is the symbol ×. While similar to a lowercase latin letter X (x), the form is properly a rotationally symmetric saltire. [1] Other signs (or even no sign) are used, according to mathematical context or national convention.
The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.
Per earlier discussions, the lead should reflect the fact that other signs are used for multiplication. This is in the body but should be summarised in the lead. This is a draft for discussion, observations and suggestions are invited. The change is to give equal status in the infobox to the four most used signs, add a prefix to the first sentence and add a second sentence: the proposed changes are written in green, except "latin letter X" which is wlinked and thus blue. --

FYI, I asked that the discussion above be closed because it was clear that nobody liked my wonderful idea. By the end, even I didn't like it either. It seemed best to just shut it down so as to start again with a clean sheet. I plan to open another informal RFC, this time based on Spitzak's idea of just having an {{ about}} hatnote but, as it is August, it is only fair that I wait a few weeks before doing so. -- John Maynard Friedman ( talk) 21:46, 6 August 2020 (UTC)
Everything I've written in this section comes either from the Cajori source, or from Oughtred's Clavis, the relevant sentence of which I translated from Latin with the assistance of Google Translate. The prior text claimed that the sign was in use before Oughtred, but when I checked the source, I saw that those "prior uses" are mentioned only for the purpose of showing that they are mistaken. A source must not be cited to support a claim that the source specifically rejects. 73.71.251.64 ( talk) 05:33, 3 August 2020 (UTC)
The Latin text, from page 10 here, is: Multiplicatio speciosa connectit utramque magintudinem propositam cum notâ in vel ×: vel plerumque absque notâ, si magnitudines denotentur unica litera.
Clavis is an algebra text and the usage of "speciosa" comes from Diophantus, who used eidos (Latin species) to mean square numbers, cubic numbers, etc., and later Vieta, who meant any quantity represented by a letter. 73.71.251.64 ( talk) 18:25, 3 August 2020 (UTC)
