## What is Permutation Combination?

"Permutation Combination Calculator" is an application that makes it easy to perform calculations for permutations and combinations commonly used in mathematics and statistics. By using this app, even those who are not good at mathematical calculations can easily perform calculations.

The app is equipped with functions for performing permutation and combinatorial calculations. In permutation calculations, you can find the number of cases where r elements are selected from n elements. Combinatorial calculations, on the other hand, allow you to find the number of cases where r elements are selected from n elements, disregarding the order.

In web-based examinations with strict time limits, reducing the time spent on calculation questions can free up time to answer other questions. By allocating your time appropriately and using the "Permutation Combination Calculator", you can take the web-based examinations efficiently and accurately.
