The answer is 3,680. There are three zeroes in 1,000 therefore you need to move the decimal point over to the right three places.
            1 0   0 0
          x   3 . 6 8
       ------------------
            8 0   0 0   
         6 0 0   0 
   + 3 0 0 0 
-------------------------     
      3 6 8 0 . 0 0 = 3, 680
