It is an important symbol that shows the relation of two quantities and you can use them in the document processor. However, you must use the correct source code to write a less than or equal to symbol in LaTeX. Let’s see how to write and use this symbol easily.

**How to Write a Less Than Or Equal To Symbol in LaTeX**

First, start with the primary source code, \leq, to write a less than and equal to symbol in the document processor. Here is an example to use this symbol:

\begin{document}

$X\leq 4$

\end{document}

**Output:**

Let’s use another example to represent the relation between A and B variables with a number. Here is the following source code that shows the relation:

\begin{document}

$$A\leq B$$

$$A \leq B \leq 7$$

\textbf{Explanation:}

\\ In the above expression, the value of A and B is less than or equal to 7.

\end{document}

**Output: **

If you want to use the less than but not equal to symbol, use the mathabx \usepackage and \nleq source code. You can use the following source code for the symbol:

\usepackage{mathabx}

\begin{document}

$$A\nleq B$$

$$A \nleq B \leq 5$$

\end{document}

**Output:**

**Conclusion**

In this tutorial, we explained how to use the less than or equal to symbol in LaTeX. We also used the different examples to explain everything about the symbol. This tutorial will help you learn about the less than but not equal to symbol and the source code to use in a LaTeX document.
