The permutation calculator below will help you find the number of permutations.
Use it only when the order of things is important.
Example of permutation
A club has 20 members
The members want to elect a president and a vice-president to be in charge of the club
Here order does matter since being the president of the club is more important than being the vice-president.
To find out how many different ways you can elect a president and then a vice-president, use the permutation calculator above
