*lightbulb_outline *This question type can be used in a digital test only.

The mathematical equation question is used when students need to answer a question by using an equation. Grading of this question can be done manually or automatically by making use of the equation solver.

## Create a mathematical equation question

- Click the
*domain***School name**in the menu on the left. - Click on
*label_important***Courses**in the menu at the top. - Click on your course or use the search bar in the
*Courses*-section. - Click on your assignment or create a new assignment.
- Click
**New exercise**, fill in a name and click**Save**. - Click
**New question**and select**Mathematical equation**. - Formulate the question in the question box.
- Fill in the amount of points the question is worth.
- Click the dropdown menu
**Equation solver***and select**Review manually**or**Use equation solver**. - If the equation solver is selected, click the
**Pencil-icon**and write the equation. Click the dropdown menu**Equation operation**and choose the operation (See equation operations below). - Click the
*more_vert***-icon**for more options. - Click

Equation operations

**Solve**Solve the given equation for a specific variable. This variable should be given as well.**Simplify**Simplify the given equation to the smallest shape.**Expand**Expand the given equation. This is done for equations that contain brackets. The result will be an equation without brackets.**Factor**This operation is the opposite of expanding. The given equation will be written as an equation with brackets.**Differentiate**Calculate the derivative of a certain function f with respect to a variable x. The derivative of a function y = f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to the change of the variable x.**Integral**Calculate the integral of a certain function f with respect to a variable x on an interval [a,b].**Limit**Calculate the limit L of a certain function f of x as x approaches c.**Summation**Calculate the sum of a sequence of any kind of numbers.

## Options for a mathematical equation question

**Bonus**This marks the question as a bonus question, which means the number of points awarded with this question will be counted until the maximum amount of points achievable for this assignment is reached. The points of the bonus question aren’t included in the maximum amount of points that can be achieved for the assignment If the student answers the question incorrectly, this won’t be detracted from the number of points and the mark.**Skippable**You will first need to assign which students are exempted from answering this question within the settings of your course. You can then enable which questions can be skipped by these students. In a digital test the student will be informed they can skip the question. The number of points for this question will not be counted in their result. It is not possible to change this setting after the test has been taken.**Partial scoring**Students will receive points when their answer is partly correct. For example, if the total number of points they can receive for a question is 2 and their answer is 50% correct, they will still receive 1 point. Without this option, they can only receive 0 or the maximum number of points.

## Add a grading scheme to a mathematical equation question

- Click
**Grading scheme**in the menu at the top. - Go to the question for which you want to set the grading scheme.
- Click the
*more_horiz***-icon**and click**Edit**. - When you review the question manually, click the dropdown menu
**Grading method***and choose your method (Read more about Grading methods here) - Click the
*more_vert***-icon**for more grading options. - Click
**Save**.

Options for grading

**M****odel answer**A solution for the reviewers (and for participants when published). The model answer can be an extensive elaboration, an image, or a file.**Start with zero points**(For the points-per-criteria and rubrics grading method only)

If this option is enabled the marking of this question will always start at zero points and the points will be added up when selecting the criteria. When this option is disabled, the marking will start with the maximum amount of points that can be awarded for this question and selecting the criteria will be subtracted from this maximum. This means that the criteria should be added as minus points of the total amount. The reviewer can then select the criteria if the student didn’t meet this with their answer, so it can be detracted from the total amount of points.**Limit minimum to zero points**(For the points-per-criteria grading method only)

With this option enabled, it’s not possible to go below zero points when selecting the different criteria. It is still possible to manually adjust the number of points to go below zero with the adjustment option during the reviewing.**Limit maximum to total points**(For the points-per-criteria grading method only)

In the grading settings it’s possible to set the maximum amount of points achievable with the question, separate from the points per criteria When this number deviates from the maximum amount achievable by adding up the criteria points, this option will cap the maximum amount of points to this manually set number.

*error_outline* The answer to the operation does not have to be given, while it is calculated automatically with the operation chosen. The student will have an infinite amount of attempts for this type of question.
