# Less than and greater than symbols

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:

• 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 $\ll$.
