Another math problem...

Sorry, in writing down the problem and the corresponding solution, I
made a mistake. It's evident, but anyway...

Wrong:
> #  ab *  cb = dab             35 *  26 = 936
> #   +     +     -              +     +     -   
> # ifd + chg = eaf            179 + 258 = 437
> # ---------------            ---------------
> # cih + cge = edd            215 + 284 = 499


Correct:
  #  ab *  cb = dab             36 *  26 = 936
  #   +     +     -              +     +     -   
  # ifd + chg = eaf            179 + 258 = 437
  # ---------------            ---------------
  # cih + cge = edd            215 + 284 = 499

(wrong 35 correct 36)

Bye.
