Let's see if TeX markup works properly here:

$$
f(x) = x \* e^{2 pi i \xi x}
$$

$$
x \in \mathbb{Z}
$$

And now some inlined text $$f(x) = x \* e^{2 pi i \xi x}$$ and another one: $$g(x) = x \* e^{2 pi i \xi x}$$

And now let's have a block:

$$
f(x) = x \* e^{2 pi i \xi x}

\newline

g(x) = x ^2
$$
