Math command doesn't interpret exponential numbers (¹²³)

[Howerr]

Bug description The bot doesn't interpret exponential numbers (¹²³) by themself, only if you write them like this, for example:

x^2 or x^3

How to reproduce Steps to reproduce the unusual behavior:

1. Run s!math [any exponential math expression using the smol numbers]

Expected behavior Exponencial numbers should be interpreted the same way as ^2 or ^5.

Won't fix, thats a problem with mathjs

Well, it does output an error to the console, so we should at least handle it instead of not responding.

[Doges]

Handle it is a good idea, but i think we need to open another issue for it.

we could just use WolframAlpha, as referenced in #895
