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?
Poppy has placed 1000 pieces / 4 = 
<gadget id="calculator">1000/4</gadget>
<output>250</output>
250 pieces.
This means there are 1000 - 250 = 
<gadget id="calculator">1000-250</gadget>
<output>750</output>
750 pieces remaining.
Her mom therefore places 750 / 3 = 
<gadget id="calculator">750/3</gadget>
<output>250</output>
250 pieces.
This leaves a total of 750 - 250 = 
<gadget id="calculator">750-250</gadget>
<output>500</output>
500 jigsaw pieces left to be placed.

<result>500</result>
