Arithmetic questions enable you to assess users' knowledge and comprehension of mathematics and number theory. You can ensure each respondent receives a unique question by including variables enclosed with curly braces that randomly generate numbers within the problem. For example, if you set variables x, y, and z with a Min 1 to Max 5 number range in 1-step increments, the question “You have {x} green marbles, {y} red marbles, and {z} blue marbles. How many marbles do you have in total?” will randomly generate a rational number (1, 2, 3, 4, 5) for {x}, {y}, and {z}.
As a best practice, D2L recommends that you create long answer (LA) question types for arithmetic problems that require users to demonstrate their calculations and show their work.
