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
