print ` (2x) (x + 2)` as ` 2x (x + 2)`

print (2x) (x + 2) as 2x (x + 2)

I don't think 2x needs parens - it's already seen as a unit imo - and I think it's like another 'being aware of coefficients' thing and that the brain really does parse it differently

You noted that for this change we'd want to make sure we can maintain the invariant that parse(mathStr) == parse(print(parse(mathStr)))

(this isn't super high priority for me since it doesn't come up that much)

@evykassirer to verify the AST that we want to print is:

(mul (mul 2 x) (add x 2))

yup!
