When creating an assessment, you can create a Formula assessment question in Quizzes.Next. In a Formula question, students need to type in the correct numerical answer.

## Add Question Title and Stem

In the **Question Title** field [1], add a question title. Question titles are optional and are not visible to students.

In the **Question Stem** field [2], add the question stem. The question stem contains the question and, if necessary, additional instructions and information. You can use the Rich Content Editor to format and add content to your question stem.

## Add Variable Answers

To add variable answers, type the question in the **Question** field [1]. After typing the question with the variable, parameters to define the formula will appear [2]. Set the variable answers for the formula. Specify the minimum [3] and maximum [4] values for the variable. Select decimal places in by using the increase or decrease arrows [5].

Type the formula definition in the formula field. Make sure the formula does not contain any brackets or equal signs.

## Generate Possible Solutions

In the solution field, specify the number of possible solutions you want to generate [1].

In the error margin of field, enter the margin of error for the student's answer [2]. Responses are based on relative error in addition to absolute error. Margins of error can be created as a percentage or as a point value (up to three decimal places).

Click the **Generate** button to view final answer [3].

## View Possible Solutions

Possible solutions will process according to the number of value combinations.

## Add Point Value
