SpeakWeb vs Combinatorics PRO

Until today, the self-learning method has been about reading with your eyes or taking notes by hand. How about grafting hearing as well? You can read out the learning content while recording, and play it back. You can type it with your keyboard, without using paper and a pen. Reading the text out loud or typing it out will definitely help the text last longer in your memory. - Listening through TTS (Text-to-Speech) - Speaking through recording - Writing through keyboard - Background playback “Even in situations where you can’t see the screen, you can read books just like listening to music” - Link to Google Translate “When reading a document written in a foreign language, you can translate it right away” - Web-site, Text, PDF - iCloud Use SpeakWeb to improve your learning efficiency!

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. [ 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
