Additionally:
- voice input of the task and the answer are available (voice calculator);
- three switchable windows for working with three tasks;
- saving examples in memory (in automatic saving mode or at the user's choice);
- it is possible to print the solution or save it in a file;
- groups of screen elements, including the keyboard, are scaled separately for optimal settings for different screens;
