Formula Questions need more flexibility
The formula questions do not provide enough necessary flexibility for mathematics questions. Reverse engineering of questions to allow variables in the questions to be generated from formulas based off expecting answers, which is making it impossible to design some questions to assess specific outcomes.
Ranges of values for variables in unreasonable, too, particularly for simple divisions when you do not want the denominator to be zero.
Realisations of questions to be created from formula questions should not be set at any maximum, but rather created in live-time with non-answers flagged to question authors to modify questions. In order to manage this, questions would need to be set at one at a time and if the error occurs, then Quizzes should be set to produce a duplicate realisation.
