message: what does "equal" mean without begging the question? —The preceding unsigned comment was added by 69.138.62.148 (talk • contribs) .
:The following argument is due to Bertrand Russell (who used it against defining the word good) and I'm no doubt presenting it badly, but here goes: You are obviously familiar with the word equal already or you would not have worded the question that way. Therefore, if I answered you with a dictionary definition like "as great as, the same as, alike in quantity or value", you would gain no new information and call it "begging the question". What you're really looking for is some non-trivial statement about equality, like "two things are equal if they can be exchanged without consequence in all circumstances", but that's not really a definition, it's a statement about the concept equality that doesn't have much to do with the meaning of the word equality itself.

replies: text: It depends on the context.  You are right that the string "2+2" is not the same as the string "4".  But the number 2+2 is the same as the number 4.  Two elements of a set are equal if they are the same element of that set.  Sympleko (Συμπλεκω) 22:05, 23 August 2010 (UTC)

message: This article already describes the use of = in programming languages, and another article, Relational operator, describes the meaning in more detail than should be described here. Should any meaningful content from Equals (computing) be merged here? +mt 02:40, 19 July 2007 (UTC)

warrant a new "In Information

message: I think the equation reproduced from Recorde's book should translate as 14x+15 = 71, not 14 sqrt(x)+15=71. Indeed, the description of the picture says so. But the text of the article uses sqrt, in English and also in several other languages. I don't dare to change it without being reassured by some of you. Please.  —Preceding unsigned comment added by 79.145.149.118 (talk) 21:34, 27 February 2010 (UTC)

message: Whilst trying to get information about various alternatives to the Equals sign that are used in logic/philosophy etc.  I came upon a page in the German Wikipedia:  Das Gleichheitszeichen  It had a lovely table with any and all of the signs I might wish to use...  Except that I don't speak/read German well and so I went looking for that same page in English...  To my chagrin, I find a wholly inadequate (for my needs at least) discussion that lacks almost all of the information that the German page seems to have...  Worst of all, that lovely table isn't apparent.  Could I humbly request that those of you working in this area might wish to see what your German counterparts are doing and perhaps use what's best of their work to fortify your own?  I'd appreciate it...  Thanks...  Emyth (talk) 18:40, 19 April 2011 (UTC)

message: Languages making the former choice often use a colon-equals (:=) or ≔ to denote their assignment operator. Which programming languages use the Unicode character? I'm not aware of any. Colon (punctuation)#Computing even claims that := in programming languages is in Unicode preferably encoded as U+2254. I can see the usefulness of U+2254 in text for human consumption, but what sense would it make to use it in source code? It's not exactly easy to type, and machines care little about the typographic beauty of the code they consume.--88.73.1.22 (talk) 01:24, 15 September 2011 (UTC)

message: Can anyone point out the difference between "equal" and "approximately equal" (why would one be preferred over the other)?  because in school we are taught 2+2=4 when we should have been taught 2+2≈4... (Is that why 2+2=5 came about?). Charlieb000 (talk) 06:02, 18 January 2014 (UTC)

message: The article begins by claiming that the American version of the British "equals sign" is "equal sign".
I strongly disagree.
The phrase "equal sign" has never been standard in the United States. The standard term for the symbol "=" in the United States is exactly the same: "equals sign".
Because of the two consecutive letters S in the phrase "equals sign", it can be sometimes misheard as "equal sign". That does not make this right. 2601:200:C000:1A0:C562:18A:9D3C:C69B (talk) 21:22, 31 August 2022 (UTC)
