  Mathematics has become inescapable in modern, digitized societies: there is
hardly any area of life left that isn't affected by it, and we as
mathematicians play a central role in this. Our actions affect what others, in
particular our students, decide to do with mathematics, and how mathematics
affects the world, for better or worse. In return, the study of ethics in
mathematics (EiM) has become increasingly important, even though it is still
unknown to many. This exposition tries to change that, by motivating ethics in
mathematics as an interesting, tractable, non-trivial, well-defined and good
research area for mathematicians to consider.
