Combinatorics PRO

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.

[ Usage ]

- there are fields for entering values using a special keyboard

- multiple k values can be entered using the semicolon key

- press the check mark button at the bottom right to start the calculation

- if values are missing, the corresponding field is highlighted in yellow

- if the values are incorrect, the affected field will be highlighted in red

- a short message explains why a value is incorrect

- the entries in the history can be deleted or sorted

- if you select an entry in the history, it will be automatically loaded for the calculation

- the whole history can be deleted by pressing a button

- solutions can be shared
