## edn and s-expr syntax
Got excited about edn ("extensible data notation"), which is sort of a
formalization of extended s-expressions from closure world. Could try to stick
to a subset of this syntax to get free parsing in several languages? Maybe just
as a place to start.

## racket symalg package
<https://docs.racket-lang.org/symalg/index.html>
Every simply/basic API. Can convert to/from "algebraic expression" objects,
simple s-expr, infix, and latex. Has simplification, differentiation, and
evaluation helpers.
## Computer Algebra and Symbolic Computation books by Joel Cohen
Fairly basic. Referenced from the racket symalg docs.
## Web Math Editors
Nice simple formula editors, implemented in Javascript. Eg, fractions,
exponentials. integrals, greek symbols, etc.
