[Serious] What are your overall opinions on people who are idiots in math?

In my opinion, medieval studies is the most difficult academic subject due to the fact that one must learn six or so different languages, not only in their modern form but in their middle and early forms and be able to read primary sources and other manuscripts.

Indeed. Math is simply one language. Furthermore, in spite of appearances, the notation is designed to make it easier. Not all that long ago, everything was written out in words.
