Question

Little Caesar's Pizza had a commercial on television that claimed you could buy one pizza and get another one free, with up to 5 toppings per pizza (do not count the pizza sauce or the cheese as a topping). The dialogue on the commercial went something like this. The tall person said, "5 toppings per pizza; that's 10 different pizzas to choose from." The little guy then said, "No, it's 1,048,576 pizzas." What do you think?
