Not sure where to start? These are the lessons and games we recommend most to students, parents and teachers on Basic-mathematics.com. Each lesson explains the topic in plain language, walks you through worked examples step by step, and ends with practice so you can check your understanding. Pick one below, or use the menu to find lessons on fractions, algebra, geometry, statistics and more.
The permutation calculator below will help you find the number of permutations. Use it only when the order of things is important.
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.
Just type in the box 20 for n and 2 for r
20 means number of people in the club
2 means number of people in charge
