I’d like to request the possibility of the user to type a number (or fraction, basically math related symbols and language) in a fill in text entry or fill in blanks question, and the correct answer would be decided by an interval. For example, there would be a place where we can let the program know the correct answer is anything in the interval between 1 and 2, and what the user would submit would be analysed by the program and show the feedback accordingly.
This was already mentioned 2 years ago in this support post: Math quiz type fill in the blank with a range number
Thank you for your suggestion.
