question: Teddy finished half of a 500 piece puzzle, and then started and finished another 500 piece puzzle within an hour.  How many puzzle pieces did Teddy place during that hour?
answer: Teddy did 1/2 * 500 pieces = <<500/2=250>>250 pieces.
  Teddy completed 250 pieces + 500 pieces = <<250+500=750>>750 pieces.
