The combination calculator below will help you find the number of combinations. Use it only when order does not matter.
A pizza place offers 5 toppings. You have enough money for 2 toppings
Since the order you put the toppings on your pizza does not matter, you will use combination. To find out how many different ways you can combine the toppings on your pizza, putting 2 toppings at a time, use the combination calculator above.
In this case n = 5 and r = 2
5 means number of toppings the pizza offers
2 means number of toppings you can afford
