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. [ Contents ] - all 6 variations of combinatorics - results are calculated and shown in detail - history to save the input - detailed solution - natural numbers are supported - no ads! [ 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
