Superscripts and Subscripts

MathML token

<mn>

Use ₄ only when the superscript or subscript digit has the intended mathematical role. For longer expressions, structured equation markup is safer than isolated Unicode script characters.

Characters to distinguish

  • ² — Superscript Two
  • ₁ — Subscript One
  • ⁰ — Superscript Zero

Meaning and usage

A Unicode subscript form of 4.

For Subscript Four (₄), use it in plain text for indices or chemical formulas; use MathML or LaTeX for complex notation.

Pronunciation: subscript four

How to type Subscript Four

Windows
Open Character Map and search by name or Unicode U+2084.
macOS
Open Character Viewer with Control–Command–Space and search by the symbol name.
Microsoft Word
In an equation, type _{4} and press Space when Word supports the command.
iPhone and iPad
Copy and paste ₄, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
Android
Copy and paste ₄, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
Google Docs
For plain text, paste ₄ or use Insert → Special characters. For structured math, use the equation editor and verify _{4}.
Excel
Paste ₄ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.

Common mistakes

  • Unicode superscript or subscript glyphs such as ₄ are plain text; use structured LaTeX or MathML scripts when nesting, accessibility, or reliable layout matters.
  • For plain text, copy ₄ as U+2084; for structured equations, use _{4} in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Subscript Four.

When to use ₄

  • Use ₄ in plain text when a Unicode character is appropriate and the destination preserves U+2084.
  • Use _{4} in an equation editor when mathematical spacing or structure matters.
  • Define the local meaning when Subscript Four is used in super sub with a field-specific convention.

Look-alikes and related characters

  • ² — Superscript Two
  • ₁ — Subscript One
  • ⁰ — Superscript Zero

Font and compatibility notes

Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
