Introduction to the \leq TeX command

The \leq command is a TeX command that is used to typeset the "less than or equal to" relation symbol. It is part of the standard LaTeX packages and can be used in both inline and display math mode.

Syntax

The syntax of the \leq command is as follows:

a \leq b

where a and b are mathematical expressions. The command produces the "less than or equal to" symbol (≤) between a and b.

Example

Here is an example of how to use the \leq command in LaTeX:

\documentclass{article}
\begin{document}

The relation $a \leq b$ means that $a$ is less than or equal to $b$.

\end{document}

This will produce the following output:

The relation $a \leq b$ means that $a$ is less than or equal to $b$.

Related commands

There are several related commands in TeX that are used to typeset relation symbols:

• \leqslant: Similar to \leq, but with a slightly different shape of the symbol.
• \leqq: Similar to \leq, but with a double line instead of a single line.
• \leqno: Puts the symbol on the left-hand side of the equation instead of the right.

Conclusion

The \leq command is a useful TeX command for typesetting "less than or equal to" relation symbols. It is simple to use and can be used in both inline and display math mode.
