LaTeX Math Symbols FAQ

How to write symbol in LaTeX?

Type its command in math mode, for example $\leq$ for ≤ or $\infty$ for ∞. Click any tile above to copy the right command.

How to write degree symbol in LaTeX?

Write $90^\circ$ in math, or load gensymb and use \degree. With siunitx, \ang{90} prints 90° with the correct spacing.

How to write real number symbol in LaTeX?

Load amssymb and write \mathbb{R}. The same command gives ℕ, ℤ, ℚ and ℂ for the natural, integer, rational and complex numbers.

How to write for all symbol in LaTeX?

\forall gives ∀ and \exists gives ∃. For "does not exist", load amssymb and use \nexists, or write \not\exists.

How to write element symbol in LaTeX?

\in gives ∈, \notin gives ∉ and \ni gives ∋. Subsets use \subset and \subseteq, all in plain LaTeX.

How to write symbol in LaTeX Overleaf?

Just as in any LaTeX editor: type the command in math mode. Overleaf has amssymb and amsmath installed, so load them in the preamble when a symbol needs them.

How to write percent symbol in LaTeX?

% starts a comment, so write \% instead, in text or maths. The same goes for \&, \#, \$ and \_.

How to write approximate symbol in LaTeX?

\approx gives ≈. Close relatives are \sim (∼), \simeq (≃), \cong (≅) and \propto (∝).

How to type union symbol in LaTeX?

\cup gives ∪ and \cap gives ∩. For large unions over an index, use \bigcup and \bigcap, which take limits like \sum.

Does not equal symbol LaTeX?

\neq (or \ne) gives ≠. Most other relations can be negated by putting \not in front, as in \not\equiv.

How to write infinity symbol in LaTeX?

\infty gives ∞, as in \lim_{x \to \infty}. No package is needed.

Does not divide symbol LaTeX?

\mid gives ∣ for "divides". For "does not divide", load amssymb and use \nmid.

How to write sum symbol in LaTeX?

\sum gives ∑. Add limits with \sum_{i=1}^{n}; in displayed equations they sit above and below the sign.

How to bold symbols in LaTeX?

Use \boldsymbol from amsmath or \bm from the bm package, for example \bm{\nabla}. \mathbf only works on letters and digits.

How to insert end of proof symbol in LaTeX?

Inside amsthm's proof environment the box □ appears by itself. Elsewhere, use \qed, or \blacksquare from amssymb for a filled box.

How to write vector symbol in LaTeX?

\vec{v} puts a small arrow over v, \mathbf{v} or \bm{v} sets it bold, and \overrightarrow{AB} draws a long arrow over several letters.

How to write greater than symbol in LaTeX?

Type > and < directly; \geq (≥), \leq (≤), \gg (≫) and \ll (≪) cover the rest.

How to write mod symbol in LaTeX?

Use \bmod for a \bmod b, \pmod{n} for (mod n) after a congruence, and \equiv for ≡.

How to write micro symbol in LaTeX?

In maths, \mu gives μ. For units, siunitx's \micro or upgreek's \upmu give the upright micro sign units need.

How to define a new symbol in LaTeX?

Use \newcommand in the preamble, for example \newcommand{\R}{\mathbb{R}}, then write \R wherever you need it.

How to add square root symbol in LaTeX?

\sqrt{x} gives √x and \sqrt[3]{x} gives a cube root. The sign stretches to fit what is inside.

Is there a LaTeX math symbols cheat sheet?

This page works as one: every symbol here is searchable and copies with a click. For a printable reference, the Comprehensive LaTeX Symbol List on CTAN covers thousands more.

Which packages do LaTeX math symbols need?

Most LaTeX math symbols are built in. amssymb adds ℝ, ∄, ∴ and many arrows; amsmath adds \iint and \binom. Each tile names the package it needs.

Can I use math symbols in normal text or section titles?

Wrap them in math mode, as in $\leq$, which works inside sentences and titles. With hyperref, add \texorpdfstring in titles so bookmarks stay readable.

Do LaTeX math symbols work in Word or Matplotlib?

Word's equation editor accepts many of the same commands, such as \infty and \leq. Matplotlib renders them in labels written between dollar signs.

How do I change the space between math symbols?

Add space with \, (thin), \: (medium), \; (thick) or \quad, and remove a little with \!. LaTeX already spaces relations and operators itself.

How do I make a math symbol upright instead of italic?

Wrap letters in \mathrm, and declare operator names with \operatorname or \DeclareMathOperator so they are upright and spaced correctly.

How do I write brackets, absolute value and norm in LaTeX?

Use \left( and \right) for brackets that grow, \lvert x \rvert for absolute value, \lVert v \rVert for a norm and \lfloor x \rfloor for the floor.

How do I write expected value and mean in LaTeX?

Write \mathbb{E}[X] or \operatorname{E}[X] for expected value, and \bar{x} for a sample mean.

Can I find a LaTeX symbol by drawing it?

Not here; this page searches by name or symbol. Detexify is a free site where you sketch a symbol and it suggests matching commands.

How do I copy a symbol command from this page?

Click a tile and its command goes to your clipboard, with a tick to confirm. Search by name, such as approx, or by the symbol itself.

Should I use \times or \cdot for multiplication?

\times (×) is usual for dimensions and cross products, \cdot (⋅) for dot products and plain multiplication. Follow your field's or journal's style.
