In current buffer evaluation is easy with:

{M-x lisp-interaction-mode}

as then with C-j you get result in the next line:

(+ 2 2)
4

Otherwise in any buffer one could bind eval-print-last-sexp to a key
to get same effect, then undo to delete it.

I am often inserting things like pricing by replacing the current
expression:

(defun replace-last-sexp ()
  "Eval last sexp and replaces it in the buffer with its result."
  (interactive)
  (let ((result (eval (elisp--preceding-sexp))))
    (kill-sexp -1)
    (insert (format "%s" result))))

Then when writing emails I write sometimes expression that replaces
itself even with complicated sentences something like this:

With 3 machines and 10 hours of work per day and grade of 0.70 we
can make 1260.00 units, equivalent to US $64863.38 per month.
