comment Book/tutorial recommendations: acquiring math-oriented reading proficiency in German
There is also a new sister-forum exclusively for German: german.stackexchange.com - it is not exclusively for math-oriented German but there are many well qualified persons that are eager to answer your questions (me included :-)
