0 in algebraic equations

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)

Terminology

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)

Zero point energy

I have removed discussion of zero point energy, because, while it is the lowest energy state of a system, it still has a non-zero amount of energy. Thus, I don't think its relevant here. Riverskip (talk) 01:41, 18 June 2026 (UTC)

History section later in the article

I have moved the history section later in the article, after the mathematics section. I don't know the exact best ordering, but the math section should be beffore the history section, to allign with the order of importance. Riverskip (talk) 03:25, 22 June 2026 (UTC)

Add Rigvedic decimal enumeration context to the India section

The India section jumps straight to Pingala, but there is useful earlier context that seems worth mentioning. Bavare and Divakaran's study of number names in the Ṛgveda finds a systematic decimal nomenclature and interprets it as an oral form of place value. The paper is also careful not to claim that the text contains a mathematical zero, so it gives us a clean way to explain the earlier decimal framework without treating decimal enumeration, a written placeholder, and zero as a number as though they were the same thing.

Could the following be added as the first paragraph of the India subsection?

The Ṛgveda contains a systematic decimal nomenclature. In a study of its number names, Bavare and Divakaran interpret the system as an oral form of the place-value principle: names for 1–9 and powers of ten are combined using grammatical rules to denote compound numbers, with the largest just under 100,000. They also note that the Vedic corpus provides no evidence for a mathematical zero, which this oral system did not require.

That wording follows the source's distinction while filling in an important part of the Indian chronology. Oughtist (talk) 09:54, 8 September 2026 (UTC)

Hello Oughtist, you can now make the requested changes yourself, as your account is now auto-confirmed. I'm deactivating this edit request.  Ivecos (t) 20:30, 10 September 2026 (UTC)
