Substitute digits for the letters to make the following relation true.

        S O M E 
      + G O O D 
     ---------- 
      I D E A S 
     ---------- 

Note that the leftmost letter can't be zero in any word. Also, different digits represent different values.

8795
+4773
-----
13568

I couldn't find an elegant way to solve this so ended up using trial and error with a modicum of logic thrown in.

I started on the basis that I=1, and then worked through the options for increasing values of D. This solution worked at D=3 so there may be more for higher values of D, I'll have a look tomorrow.
