Hi Jose,

Indeed ConTeXt contains all the plain TeX commands and you can use 
them (in this case \sum). So these formulas give what you want
$\sum_{i=1}^n x_i$ (for the summation)
$\prod_{i=1}^{i=n} (1+x_i)$ (for the product), and so on.

For the displayed version you can use either
$$\sum_{i=1}^n x_i$$
or
\startformula
\sum_{i=1}^n x_i
\stopformula

Best regards: OK
