Well, Lisp has excellent arithmetic capabilities. Bignums, Floats, Ratios, Complex numbers built in.

Infix notation is provided by macros or read macros.

Infix notation is provided by math packages on top of Lisp: Macsyma, Reduce, Derive, Axiom, ...

Those provide REAL extensive math syntax capabilities, not just what typical programming languages provide.

Sloppy me. I would of course be referring to arithmetic syntax or notation. And you make my point exactly: there is many ways to express arithmetically heavy operations in a natural, readable way.
