# Mathematics

To add mathematics, such as equations, use one of the math editors. There are two available in Paligo:

• Free built-in math editor based on MathQuill

• MathType. This is provides more advanced mathematical features but requires a Wiris MathType subscription.

The following sections explain how to choose which math editor to use, and how to access each editor.

Paligo's built-in editor, based on MathQuill, is the default math editor. It is free to use and you can use it to create simple equations. If you need to use more complex equations, you can use the MathType editor instead, although this does require a Wiris MathType subscription.

To choose which math editor to use:

1. Edit a topic.

2. Select the Editor Settings icon (cog).

3. Select the Editing tab.

4. Scroll down to the MathType Editor section.

5. Choose the math editor you want to use for this topic:

• Check the Use the MathType editor for editing math expressions box if you want to use MathType

• Clear the Use the MathType editor for editing math expressions box if you want to use Paligo's built-in math editor.

6. Select Save Settings to confirm your choices.

### Note

The MathType editor is backwards-compatible with the built-in editor, so you can switch between them if needed.

The built-in math editor is a customized version of MathQuill. It has less features than the MathType editor, but is free to use in Paligo.

The built-in math editor is enabled by default. To use it:

1. Edit a topic and use the element context menu to add an equation element or an inlineequation element.

To access the element context menu, press Alt and Enter (Windows) or Option ⌥ and Enter (Mac).

2. When you have added an equation element or inlineequation element, double-click it to display the math editor.

### Note

If you see a more complex math editor, then the MathType editor is enabled for your topic. This is a more complex editor and if you have a subscription, you can use that instead. If you do not have a subscription, you can set your topic to use the built-in editor.

3. Use the math editor's features to create the equation.

The editor is based on MathQuill, and you use simple commands to write your expressions. For example, \sqrt to type a square root.

Type a space after each "backslash command".

You can enter some commands, such as fraction and multiplication, by using commonly used keys, such as / and *. The editor will generate proper math display of these.

Below are some examples of commands you can use.

### Tip

For a more complete list of commands, see this web site: List of math commands

There are also many videos on YouTube showing the basics of these commands: YouTube introduction videos for compatible math commands

### Note

Note that if you are going to publish to help desk, you cannot use math expressions there, as the HTML tags are not allowed on those platforms. You may then have to make a special version of that content for publishing there.

5. Repeat this process for each equation that you need.

6. Select Save.

To use the MathType editor, you need:

• A Wiris MathType subscription

• To provide Wiris MathType with the URL of your Paligo instance. They need this to set up the integration with Paligo in their system.

• To enable the MathType editor in Paligo (see Choose a Math Editor).

When these things are in place and Wiris have confirmed that they have set up the integration, you can use the MathType editor.

### Note

You cannot use the MathType editor until Wiris have set up the integration for you.

To use MathType:

1. Edit a topic and use the element context menu to add an equation element or an inlineequation element.

To access the element context menu, press Alt and Enter (Windows) or Option ⌥ and Enter (Mac).

2. When you have added an equation element or inlineequation element, double-click it to display the MathType editor.

3. Use the MathType editor to create the equation you need and select Insert to add it to your Paligo topic.

To learn how to use the MathType editor, see the official MathType documentation.
