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.

## How to create a mathematical equation question

- Create an assignment.
- Click
**New exercise**, fill in a title and click**Save**. - Click
**New question**, select**Mathematical equation**and click**Save**. - Fill in the question description.
- Click the drop-down button
**Review method**and choose**Review manually**or**Use equation solver**. - When the equation solver is chosen, click the
**Pencil-icon**and write the equation. Click the drop-down button**Equation operation**and choose the operation. - Click the
*more_vert***-icon**at the top of the question and you can use various options. - Click
**Save.**

Options for a mathematical equation question:

**Bonus**This marks the question as a bonus question.**S****kippable**This question will not be taken into account for the grades of exempt students.

#### 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.

## How to 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 drop-down button
**Grading method**and choose your method:**Points per criterion**:- Click
**Save**and click the*add***-icon**. **Fill in**the criterion description, set the number of points and click**Save**.*Repeat this for all criteria*- Click the
*more_horiz***-icon**and click**Edit**. - You can use the
**Calculate points**-button to calculate the maximum points. The points of all the criteria will be summed up automatically.You can manually set the maximum number of points.*Or*

- Click
**Slider**:- Set the maximum number of points.

**Rubrics with levels**:- Click
**Save**and click the*add***-icon**. - Fill in the name of the level and fill in the level description.
- Set the number of points and click
**Save**. *Repeat this for all criteria*- Click the
*more_horiz***-icon**and click**Edit**. - Set the weight of the levels.
- You can use the
**Calculate points**-button to calculate the maximum points. The points of all the criteria will be summed up automatically.You can manually set the maximum number of points.*Or*

**Save**.

Options for grading:

**Grading description**A solution for the reviewers (and for students when published). The grading description can be an extensive elaboration, an image, or a file.**Start with zero points**(For the points-grading method only)

Select this option to allow all students to start with zero points before grading.**Limit minimum to zero points**(For the points-grading method only)

Select this option to allow all students to receive no negative points for this question.**Limit maximum to total points**(For the points-grading method only)

Select this option to allow all students to receive a maximum amount of points of the total amount of points for this question.

*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.
