You can create mathPad questions that use Symbolic mode to evaluate arithmetic and
algebraic expressions, but not equations, for equivalency to the answer. Because responses
are graded for mathematical equivalency, the form of the student's response is not
considered. For example, 4x+12 would be equivalent to
(x+3)4.
 Prerequisites
 Evaluation Modes for Math Questions
Note: Do not require your students to use function notation in
an answer. WebAssign^{®} cannot grade answers that use function notation.
To create a mathPad question using Symbolic mode:

Click
.
The Question Editor opens.

In Name, type a name for the question.

In Mode, select Symbolic.

In Question, type your question.
 Use the answer placeholder string <_> to specify
where the answer box should be displayed.
 Be sure that your question identifies any variables that the student
should use in their answer.

In Answer, type the following items on a single
line:
<eqn $PAD='devmath'; ''>variable_list:answer_key
where variable_list is a commadelimited list of the
variables used in the answer key, and answer_key
specifies the correct answer to the problem in symbolic notation. For
example:
x_1, y_1, x_2, y_2: sqrt((x_1x_2)^2 + (y_1y_2)^2)
Note:
 If an answer extends beyond the right side of the
Answer box, it is wrapped to the next line, but it is
still considered a single line so long as you do not press
ENTER.
 For information about specifying answer keys for Symbolic questions,
see Create Answer Keys for Questions Using Symbolic Mode.
 Optional:
Type a Solution.
The solution helps your students understand the steps they need to take to
determine the correct answer to the question. Your assignment settings
specify when to show the solution.

Click Test/Preview to test the appearance and behavior
of the question. See Test Questions.

Click Redisplay to show certain kinds of errors in the
Display section of the Question Editor. Make any needed changes to your
question.
 Optional:
Click Show Additional Information and change the
question's sharing permission or add descriptive information.
 By default, other instructors can use your question only if you provide
them with the question ID, and only you can edit the question or find it
in search results. To change the permission, see Share Questions With Other Instructors.
 If you make your question publicly available, you might want to provide
descriptive information to help others search for it. See Add Search Metadata to Questions.

When your question displays and functions correctly, click
Save.
WebAssign assigns it a unique question ID (QID), which is displayed in
parentheses after the question name.
You can use your question in an assignment and see it in your
My Questions list only after it is saved.
