Infix Notation Macros In Common Lisp

I want to introduce some normal mathematical expressions to Common Lisp. For example, if I call the above macro "exp":

(exp 2 + 3) => 5
(let ((a 2) (b 5) (c 3))
  (exp 2 + 3 * a + b - c)) => 10

The following is maybe difficult, therefore I do not need it:

(exp 2 + (mod 5 3) + (log 10))

Please tell me it.

Here's a hint with cmu-afix: https://lispcookbook.github.io/cl-cookbook/arrays.html#infix-syntax

to write stuff like:

#i(result[i j] += A[i k] * B[k j])
