How do I add a Calculated question to an assessment?
A Calculated question type presents a unique calculation that requires the user to solve.
A calculated question calculates new answers for every test, based on variables whose value changes each time. The answer is based on a formula, using those variables.
A variable definition has a name, a minimum and maximum value, and a number of decimal places.
A formula definition has a name, an mathematical expression that uses the variables, and a tolerance, so that answers within that tolerance of the answer are also considered correct.
