Write your equations between two '$' dollar signs.

Inside the dollar signs use LaTeX syntax to write math symbols.

Examples:

1.

$ \int_{a}^{b} x^2 \,dx $ ## Output: Integral os x squared, from a to b, dx.

2.

$ v=\frac{\Delta{x}}{\Delta{t}} $ ##Output: v equals delta x over delta t.

​

## If you used to write equations in LaTeX, it's worth knowing that

## both double dollar signs "$$" and \begin{equation}\end{equation} 

## won't work in markdown.
