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:
|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 $\ll$.
