Writing an exam paper with Julia and Jupyter Lab

I just taught Linear Algebra, which means I need to give exams with a lot of questions about computations. I would like to have the numbers in this problems to be random, and I like to solve them with computers. (Sorry, students. Only you need to compute by hand. ๐Ÿ˜†) I have tried to use Mathematica to do so. The math parts works well. But the typesetting of Mathematica looks quite ugly....
