Sums and products

Inline \sum_{n=1}^{\infty} 2^{-n} = 1 $ \quad\quad\sum_{n=1}^{\infty} 2^{-n} = 1 $

\sum_{n=1}^{\infty} 2^{-n} = 1 $$ \sum_{n=1}^{\infty} 2^{-n} = 1 $$
\prod_{i=a}^{b} f(i) $$ \prod_{i=a}^{b} f(i) $$

Assume we have the next sets

$$` S = \{ z \in \mathbb{C}\, |\, |z| < 1 \} \quad \textrm{and} \quad S_2=\partial{S} $$
