- TL;DR Summary
- Can't do fractions

I am trying to help a student but then I need it myself. Spending all my time writing a simple formula in this hateful Latex which ought to be a thing of the past. Not succeeding in writing the formula, to understand what was going wrong I tried the simplest expressions of the kind for fractions which I could write X/x or y/x

Oh.

Here it works!
