printing: no space after coefficients

[evykassirer]

e.g. print 4x^2 without the space

i.e. a number followed by an identifier or a identifier with exponent would have no space and assume the constant is a coefficient

Since we group adjacent letters into a single identifier 4xy^2 is actually 4 * (xy)^2. Users would have to type this as 4x y^2 which looks weird. I feel like we probably want 4xy^2 to parse as 4 x y^2 and things like xyz should parse as x y z, but well-known identifiers such as pi, sin, etc. should remain grouped. Thoughts?

[evykassirer]

agreed! I believe that's how mathjs works too

[evykassirer]

oh actually mathjs turns xyz into an unknown identifier

not sure how I feel about this - like, I could see math teachers naming their own functions maybe?

[k4b7]

I can add a way to add to the list of well-known identifiers so if there's a multi character identifier in the question, we can treat it as such.

[evykassirer]

that helps! I'd have to expose that in mathsteps, but I'm ok with that being a limitation of mathsteps for now - people can always rename their functions to one letter long function names :p

@evykassirer I got a start on this in #73.
