Getting Started with LaTeX
LaTeX uses a special "math mode" to display mathematics. There are two types of this "math mode":
- In-line math mode. In in-line math mode, we use $ signs to enclose the math we want to display, and it displays in-line with our text. For example, typing $ \sqrt{x} = 5 $ gives us
- Display math mode. In display math mode, we enclose our code in double dollar signs, and it displays the math centered and on its own line. For example, $$ \sqrt{x} = 5 $$ gives us
![\[\sqrt{x} = 5.\]](//latex.artofproblemsolving.com/f/3/1/f31612bc43dc5450f156382bdb93a4b8a6049f6a.png)
![\[\sqrt{x} = 5.\]](http://latex.artofproblemsolving.com/f/3/1/f31612bc43dc5450f156382bdb93a4b8a6049f6a.png)
Besides displaying in-line vs. displaying centered and on a new line, the two modes render differently in other ways. Note that $ \sum_{k=1}^n k^2 $ gives us 
whereas $$ \sum_{k=1}^n k^2 $$ gives us ![\[\sum_{k=1}^n k^2.\]](http://latex.artofproblemsolving.com/8/d/8/8d839b093839bf1ae5056abb0219c26b7647f6fe.png)
If, for some reason, you want the display style in in-line mode, just place at the start of your code. For example, $ \sum_{k=1}^n k^2 $ gives 
whereas $\sum_{k=1}^n k^2 $ gives
