In mathematics, the less than and greater than signs denote an inequality between two values. **These signs are easily typeset in LaTeX using the keys available in your keyboard < and > **which produce the output \(<\) and \(>\) inside math mode (they can also be used outside math mode, but the output looks slightly different).

The next table summarizes different commands for comparing quantities:

Description | Command | Output |
---|---|---|

Less than | < | \(A<B\) |

Greater than | > | \(A>B\) |

Less or equal than | \le | \(A \le B\) |

Greater or equal than | \ge | \(A \ge B\) |

Much smaller | \ll | \(A \ll B\) |

Much greater | \gg | \(A \gg B\) |

- When we want to denote that
**some quantity is less than or equal to some other, we have to use the symbol**.*≤*which is produced inside math mode with the code $\le$. Similarly, we can produce the greater than or equal symbol*≥*with the code $\ge$

- We can also denote, more qualitatively, that a
**quantity is much greater than another using the symbol \( \gg \), which can be obtained with $\gg$**. Again, we can also denote that a**quantity is much smaller than another using \( \gg \), which is obtained with $\ll$**.
