How do I create a Formula question in New Quizzes?

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

You can also duplicate Formula questions to create a new question.

**Note: **View information about Canvas Formula Quiz Question Helper Functions.

To create a question, click the **Add** button anywhere in the assessment.

Click the **Add Formula** button.

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.

Identify variables in your question by surrounding variable names by backticks. (e.g., a variable name of x can be identified by typing `x`.)

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

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

**Notes**: The Formula Definition supports the following operators: + (add), - (subtract), * (multiply), / (divide), and ^ (power).

Specify the number of possible solutions you want to generate in the **Number of solutions** field [1]. Then select the number of decimal places required in the **Decimal places **field [2].

In the **Margin type** field, select the absolute or percent margin type [3]. Enter the margin of error for the student's answer in the **+/- margin of error** field [4]. 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).

To display solutions in scientific notation, click the **Display as Scientific Notation** button [5].

To view possible solutions, click the **Generate** button [6].

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

To allow students to use an on-screen calculator for this question, click the **Show on-screen calculator** checkbox [1].

If you select this option, you can enable a basic calculator [2] or scientific calculator [3]. The basic calculator displays numbers and basic math functions (add, subtract, multiply, divide). The scientific calculator displays more options for advanced calculations.

**Note:** The on-screen calculator option is intended to be used while displaying one question at a time. If the assessment does not display one question at a time, students may be able to use the calculator for all questions.

To align the question to an outcome, click anywhere in the **Align to Outcomes** section.

If you want to save a question to use in other assessments, you can add it to an item bank.

To add the question to an item bank, click the **Add to Bank** link.

**Note:** After a question has been added to an item bank, it can only be edited in the item bank. You can still set unique point values and options in the assessment for an item bank question.

To customize the point value for the question, type the point value in the **Points** field [1] or use the arrows to increase or decrease the point value [2].

To save the question, click the **Done** button.

I noticed that display as scientific notation removes the ability to apply a margin of error to the questions, which is a huge problem because in testing I found that an answer of 1.2 would be marked incorrect against a correct answer of 1.20 and vice versa. The margin of error needs to be added to scientific notation otherwise it is useless.

The mechanism for entering scientific notation is also problematic. Most of us are accustomed to using the “E” format in calculations, such as 1.20E-2, but the formula question uses 1.20*10^-2, which is really convoluted. The formula questions need to accept both or the easier “E” format.

Hi @pcharles and @JoeBattistelli

Thank you for your comments here. From what @JoeBattistelli says, it sounds like there's a workaround for students. However, feel free to search through the Ideas Conversations forum for any Canvas feature ideas that might meet your needs.
