Try with embeded mode of calc: C-x * E (no need to mark the region)
and similar commands (J or W in place of E). You need to type C-x * E
again to exit the embeded mode.


Another solution:

  - mark the region with math expression and put it into kill-ring (M-w)
  - type SPC = SPC
  - run the calc (C-x * c)
  - type ' (apostrophe) and yank yor math expression (C-y)
  - type RET
  - type y (or C-x * y) to copy the result into buffer
  - exit calc (q)
