conversations.value: Poppy is solving a 1000-piece jigsaw puzzle. She places a quarter of the pieces on the board, then her mom places a third of the remaining pieces. How many jigsaw pieces are left to be placed?
  Give me a clear explanation.

conversations.value: Poppy has placed 1000 pieces / 4 = 250 pieces.
  This means there are 1000 – 250 = 750 pieces remaining.
  Her mom therefore places 750 / 3 = 250 pieces.
  This leaves a total of 750 – 250 = 500 jigsaw pieces left to be placed.
