Create arithmetic questions

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 written response (WR) question types for arithmetic problems that require users to demonstrate their calculations and show their work.

1. In the Question Library, from the New button, click Arithmetic Question (2+2).
2. In the General area, enter your arithmetic question details using the following supported operations, functions and constants:

   Enumerations	Description
   +,-,*,/,\,^	Basic mathematical operators
   %	Modulo (remainder) operator
   {x}^{y}	x to the power of y
   abs({n})	Absolute value of n
   cos({n})	The cosine of n (in radians)
   sin({n})	The sine of n (in radians)
   sqr({n})	The square root of n
   tan({n})	The tangent of n (in radians)
   log({n})	The log base 10 of n
   ln({n})	The log base e of n
   atan({n})	The inverse tangent of n
   sec({n})	The secant of n
   cosec({n})	The cosecant of n
   cotan({n})	The cotangent of n
   Factorial	Factorial of n, or (n!)
   exp	The power of natural log (e)
   pi	pi 3.14159 (accurate up to 50 decimal places)
   e	e 2.71828 (accurate up to 50 decimal places)

3. In the Variables area, do the following:
   • Create any variables you want to use with your question by giving the variable a Name, a minimum value in Min, and a maximum value in Max.
   • Set the number of decimals to provide in the Decimal Places drop-down list.
   • To set the system's incrementing steps as it generates numbers from the range set by the Min and Max fields, enter a number in the Step field.
