In our current Blackboard courses, there are Calculated Numeric questions, where the student is prompted to type a numerical answer, and the instructor can specify a +/- range within which the answer will be considered correct. For example, if I want students to read the temperature displaying on a picture of a thermometer, I might want to accept answers that are plus or minus 0.5 of a degree. Blackboard's Calculated Numeric option handles this.
In Brightspace, would I use an Arithmetic Question for the thermometer example? It's unclear to me how I would do that, because Arithmetic Questions seem to involve entering variables like x and y that are randomly replaced with different values for each student, and that's not what I'm trying to do in this example.
