My students often write things like F’(x) = $\int sin(x)$. Catching the
incorrect placement of $ would help them learn. Catching sin vs \sin would
be even nicer.
Your program is presumably adding \( and \) before passing to MathJax?
(Those are valid LaTeX, by the way.) could it also strip $ before and after?

A training in mathematics is a prerequisite today for work in almost
any scientific field, but even for those who are not going to become
scientists, it is essential because, if it is only through speech that
we can understand what freedom means, only through mathematics
can we understand what necessity means.
