You can use LaTeX to add math formulas to your presentation:
All you have to do is add a multi-line code block with type math
(```math
) and add your math formula there:
```math
(F f)(y) = \frac{1}{\sqrt{2 \pi}^{n}} \int_{\R^n}{f(x) e^{-iyx}} dy
```
marmota.app is using KaTeX to render those math formulas. Please refer to their documentation to find out which functions and symbols are supported.
