Calculated Formula questions present students with a question that requires them to make a calculation and respond with a numeric answer. The numbers in the question change with each student and are pulled from a range that you set. The correct answer is a specific value or a range of values. When a student views the question, the variables [x] and [y] are replaced with values that are generated randomly from number ranges that the instructor specifies.
