# [NTG-context] Problem with matematics (derivative and brackets combinations) + wrong pagenumbering

Hello ConTeXist.


I type some math now. When I use the symbol derivative in combination with symbols brackets, so the result does not look too good. Compared to the result in LaTeX output is almost unusable. It is possible to achieve a better result?


In addition, I noticed that the page numbering starts from number 2. Is it a bug or I wrong?

Thanx Jaroslav Hajtmar
