Numerical questions allow numerical responses, possibly with units, that is graded by comparing against various model answers, possibly with tolerances.
This an example of a numerical question:
In the Answers block put the possible answer(s) to the question and assign a grade. In the case of the question above: 20 in binary is 10100. Since there is not other possible answer, the margin for error is 0 and this answer also has a grade of 100%.
