## Description

Finally there is the app that provides all 6 variations of combinatorics with step by step solutions:

- permutation without repetition: Arranging elements without repetition.
- permutation with repetition: Arranging elements with repetition.
- combination without repetition: Selecting elements without considering the order.
- combination with repetition: Selecting elements with consideration of the order.
- variation without repetition: Arranging elements with fixed length without repetition.
- variation with repetition: Arranging elements with fixed length with repetition.

You only have to enter your values k and n. The values must be entered as natural numbers. The only exception is the k value for permutation with repitition. This requires several k values, which must be entered separated by semicolons.

All calculations are stored in the history. The final solution can be shared.
