Replace “Adding zero to any number leaves that number unchanged;” with “Adding or subtracting zero from any number leaves that number unchanged;” because a few extra words wouldn’t hurt, wouldn’t they? And about the “this is obvious” part, same goes for adding zero, so could we just stuff this in there? Thank you! 81.248.31.204 (talk) 00:06, 20 December 2024 (UTC)

This seems unnecessary to me. –jacobolus (t) 08:28, 20 December 2024 (UTC)

Looks done to me ("Adding (or subtracting) 0 to any number leaves that number unchanged;") and I for one like it as-is. john factorial (talk) 01:05, 10 February 2025 (UTC)

I removed {{citation needed}} from the section on computer arithmetic, not because I don't think it needs one, but because I don't know what it is asking for. If someone does know, discuss here. It might apply to the sentence on floating point arithmetic, which could site the hardware manuals for a very large number of computer systems. It might apply to the whole paragraph, including fixed point systems. There are a small number of floating point systems without a negative zero, which could also be cited.

"Zero is an odd number that equals nothing and can't be divided by itself", perhaps maybe someone should add that as a nutshell tag GimmeKittens (talk) 14:40, 2 July 2025 (UTC)

Yeah I don't think so, thanks. --JBL (talk) 17:37, 2 July 2025 (UTC)

@GimmeKittens, check out the documentation here: Template:Nutshell. The "nutshell tag" is only used on administration pages, not on in the article space. – Farkle Griffen (talk) 20:12, 2 July 2025 (UTC)

@GimmeKittens zero can exist as the property of the neutral additive integer. Anyways that is a nutshell for any serie that its byself containing this number. So yes, maybe the subjectivity in its zero number should support void terminology out its 0's significancy, and as by the way it could represent the initial positional values for real numbers in the decimal system.

I am not sure if this is been said in the article but zero is used to solve equations when there are two expressions multiplied equaling zero. If solving equation x^2+3x+4=5 you subtract five to get to 0 and get to x^2+3x-1=0 then you can do the quadratic equation to find the x. Setting an equation to zero allows you to find equations with two expressions and solutions. On another equation example with (x-2)(x+3)=0, x=2 and x=-3. This is particularly useful when dealing with quadratic equations and other complex equations. If setting an equation to zero like I said above hasn’t been mentioned in the article, where would be a good place to put it? WikiGrower1 (talk) 04:35, 29 December 2025 (UTC)

The terms qualified as "British English" are hardly that, the source given (Collins) doesn't state it either, or only for particular forms or uses. Some of them are old-fashioned or limited to specialized context, that doesn't make them "British English", not even Commonwealth English, which is what you really meant. At the same time, "null" is conspicuously missing from the paragraph, even though arguably more common and general than some others, and not surprisingly the only one actually being mentioned later (Mathematics). Your page is protected by the way. -~2026-10427-95 (talk) 16:28, 15 February 2026 (UTC)
