This idea has been developed and deployed to Canvas

Fill in the blank only allows word answer. If my students needs to enter (2sin(x)cos(x)) or something from calculus it gets confusing. If students as well as teachers are allowed to use Rich Content Editing in simple fill in the blank. I believe it will make it easier for all the chemistry and math teacher because it will enable latex typing.
For Example: This is hard to input:
Inputting: (sin(3x))/((x3)(x+3))((3sin(x)cos^2(x)sin^3(x))/(x^29)) can be very tricky and can be easily mistaken. Therefor if rich content editing(LaTex system) were to be allowed students can easily type
instead of (sin(3x))/((x3)(x+3))((3sin(x)cos^2(x)sin^3(x))/(x^29))
