                        Example

                        Reading time: 1min

                        Consider the following question:

                        with correct answer:

                        To make formulas like (0,1) interpreted as intervals, we must select the corresponding checkbox in Input options > Input syntax.

                        Notice

                        If the Intervals option is selected, we can also use the reversed notation to exclude the endpoints from the corresponding set. Thus, [-2,+∞[ will also be accepted.

                        Finally, intervals are conceptually equivalent to inequalities, but internally (in the Algorithm), they are different data types. We need to use the Equivalent equations validation method if we want students to answer either intervals or inequations. Alternatively, student answers must be the same type as the correct answer.
