typing math symbols and exponents in RISE quiz option?? How do you do this?

Thanks Alphonso - I'm not familiar with the Word equation editor - when I was testing I just looked at adding in those symbols and superscripts just using the insert option in a Word doc and a Google doc and copy and paste it from there. It did come through to ELH and also into my Rise course. It seems that the Word equation editor is including some additional formatting options that are being striped out as a part of the copy/paste process?  

A colleague was able to find some unicode characters for the multiplication symbol and the superscript 6 that worked (just a bit of web research to track these down).
