Looking at the second line, I want to get the following latex text output.

① -2^2 = 4 ② (-1)^101 = -101 ... ④ (-\frac{1}{2})^2 = -\frac{1}{4}

can I take some helps ?

Hi @ai-motive, and thank you for your interest in this library. It does not currently provide any special support for mathematical expressions or LaTeX output. Closing this issue for now, but if someone in the community would like to try adding this support, feel free to discuss it here.
