- Put the symbol in maths mode: inline as
$\alpha$, or in a display block for a full equation. - Commands that take an argument wrap it in braces, like
\sqrt{x} or \vec{v}. - Paste into Overleaf, a
.tex file, Jupyter, or anywhere that renders LaTeX maths.
Frequently asked questions
How do I write Greek letters in LaTeX?
Use a backslash and the letter name in maths mode: \alpha, \beta, \pi, and so on. Capitalise the name for the uppercase form where it differs, like \Gamma, \Delta and \Omega.
How do I write the plus or minus sign in LaTeX?
Use \pm for plus or minus and \mp for minus or plus, for example x = \pm\sqrt{2}.
How do I write the real numbers symbol in LaTeX?
Use \mathbb{R}. The same blackboard-bold command gives the other number sets: \mathbb{N}, \mathbb{Z}, \mathbb{Q} and \mathbb{C}.
How do I write less than or equal to in LaTeX?
Use \leq for less than or equal and \geq for greater than or equal. For not equal, use \neq.
How do I write a vector or a hat in LaTeX?
Put the accent command around the letter: \vec{v} for a vector, \hat{x} for a hat, and \bar{x} for a bar or mean.
