Ulrich Görtz- Numbas at mathcentre.ac.uk

Professor of Mathematics at the University of Duisburg-Essen (Germany). My research is on arithmetic geometry.

So far, I have used Numbas mainly for my Linear Algebra classes (winter 2020/21, summer 2021) and for Mathematics for Economists (winter 24/25, and once more in the winter 25/26).
