## Background

With the math question exercise type it’s possible to define/create a mathematical problem that is ready to be solved by candidates. You can leave a part of the problem blank to be filled in by the candidate. Here is an overview of the math editor in this question type.

All mathematical symbols and signs have been split up in categories. You can select a category by clicking the list:

## Procedure

Proceed as follows to create a ** Math** item:

- Right click the folder in which you want the
**Math**item to appear. - Select
**New item**.

**Result:**The screen**Make new item**appears - Select the item type
**Math**item. - Give it a name.
- Click
**OK**.- Open the tab
**Properties**to add or change the metadata of this item. - Open the tab
**Content**and click on the text icon to add a text field or the asset icon to add an image, sound or video , … .

- Open the tab
- Select an operation from the operator bar indicated in red below.
- Add numbers in the empty areas.
**Tip:**- Selected fields are indicated with a blue border.
- Blank areas (the part the students need to fill in) are indicated with an orange border.

- Select the whole formula by clicking the largest field.

**Result:**The whole formula is indicated with a blue border (see below). - Press
**=**.

## Adding the solution

Proceed as follows to add the solution to a **Math** problem:

- Click on the
**Solution**tab at the top of the editor.

**Result:**The**solution**tab at the bottom of the page will open. - Enter the solution for this example.
- Set the score in the
**Score**tab below. - The default score setting = 1.
- If the solution contains more than one answer field, you can evenly distribute the score between the answer fields (see, example below).
- You can add multiple correct solutions if necessary.
- Save the
**Math**formula.

Students/candidates will see this in the **Edumatic** player:

## Creating a Fill in an operator exercise

Proceed as follows to create an exercise in which a student/candidate needs to fill in an operator (plus, minus, is element of, less then,… ):

- Click the
**Fill in an operator**button.

**Result:**3 question marks appear in the editor. - Fill in two numbers and leave the operator free (purple border).
- Finish up the formula by typing
**="**solution**"**("=4" in the example below). - Add the operator in the
**Solutions**tab.

You can choose between the**Basic**and the**Advanced**operators.

## Creating a formula from a LaTeX formula or edit the formula.

To create a formula from a LaTeX formula and edit the formula, proceed as follows:

- Click
**Paste formula**in the editor to paste a formula (in LaTeX) directly into the item.

**Result:**A pop-up appears. - Paste or type your formula into the text field.

**Result:**If possible, a preview of the code you posted will be shown. - Click
**Ok.** - Click
**Edit formula**to edit the formula in**LaTeX**.

## Working with multiple formulas in one item

To add more than one formula inside one item, proceed as follows:

- Click the
**+Problem**button to add a formula.

**Result:**On the left, a new column is added. - Switch between two (or more) formulas in the column by selecting them.
- Add as many problems as necessary.

Delete a formula by clicking the**Red stop**icon.

**Tip: **Choose how the problems will be presented by setting the number of columns in the **Question** tab.

- Open the
**Question**tab at the bottom of the screen. - Set the number of columns.

Example of 4 problems that are shown in 2 columns in the **Edumatic** player:

## Setting the possible operators for candidates in the Edumatic player

To choose which operators the candidate can use to solve the problem in the Edumatic player, proceed as follows:

- Open the
**Presentation**tab at the bottom of the screen. - Select
**All**in the dropdown field.

**Result:**Students/candidates will have all the operators available in the Edumatic player.

Proceed as follows to make a custom template:

- Click on an operator to deactivate.

**Result:**The operater is greyed out, meaning it will not be shown as an option to the students/candidates. - Click again to activate an operator.

**Result:**The operator turns green and is reactivated. - Repeat previous steps until the desired result is reached.
- Save your custom template.
