Hello list, As a new user of ConTeXt, I have some trouble on trying out various mathematics modules. I tried to use the nath module by directly including `\usemodule[nath]` in my source file. It seems that the module is not loaded. I read through the wiki page and found that nath is not included in the TeX Live distribution, but I failed to find a way to install it. Also, when I hunted through the wiki articles, it stated that the newmat module is included by default, but I never find it in my TeX Live 2018. Am I missing something or is the wiki outdated? By the way, I am looking for a "battery included" math module, which provides predefined macros like the absolute value symbol, derivative, and partial derivative. Any recommendation or advice on this? Thanks! Shuxian Wang
