You can use a decimal comma, for example 2,5*4. Percent works, for example 100*20%. Use semicolons in functions, for example max(2;5). Trigonometry follows the selected setting. With degrees, students can write for example sin(30), cos(60), and tan(45). If the input contains =, it is automatically solved as an equation. Variables can also have several letters, for example kr or price. The system also checks for missing parentheses, empty exponents, and simple typing errors.
