In LaTeX, the less than symbol < is used to denote inequality. However, there are situations where we need to indicate that something is significantly smaller than another. For this purpose, LaTeX provides additional symbols.

If something is much smaller than another, we use the command `\ll`

. And if something is very much smaller, we can use the command `\lll`

. However, it's important to note that `\lll`

requires the **amssymb** package to be included in the document.

### Example for Less Than and Much Less Than

\documentclass{article}
\begin{document}
a < b \\
$a < b $ \\
a much less than b \\
$a \ll b $ \\
\end{document}

### Example for Very Much Less Than

This LaTeX example showcases the use of the mathematical symbol "very much less than" (

`\lll`

), which indicates that one quantity is significantly smaller than another.

\documentclass{article}
\usepackage{amssymb}
\begin{document}
a < b \\
$a < b $ \\
a much less than b \\
$a \ll b $ \\
a very much less than b\\
$a \lll b$\\
\end{document}

In these examples, we've shown how to use the less than symbol <, the `\ll`

command for much less than, and the `\lll`

command for very much less than. We've included both the basic usage and usage with the **amssymb** package for the `\lll`

symbol.
