<human>:  At a pool party, there are 4 pizzas cut into 12 slices each. If the guests eat 39 slices, how many slices are left?
<bot>: How many slices are there? ** There’s a total of 4 x 12 = <<4*12=48>>48 slices.
How many pieces are left? ** After the guests eat, there are 48 - 39 = <<48-39=9>>9 pieces.
