Math formulas

Mindomo allows you to add mathematical expressions directly into your diagram using KaTeX syntax . This is useful for visualizing equations, functions, or technical content in educational and professional diagrams.

Note

A Premium account is needed to use the Math Formula functionality.

How to Add a Math Formula

1. Click on a topic in your diagram.

2. Select ”+” button under the selected topic.

3. Click on the “√” (Formula) icon from the expanded menu.

4. The default math formula has been added: {{math:f(x, y) = x^2 + y^2}}.

5. Upon saving, Mindomo renders the formula directly within the topic.

How to Edit Math Formulas

1. Click on the math formula again.

2. Replace the expression after “math:…” using the KaTeX syntax.

3. Add multiple formulas to the topic using the same syntax. The “√” button will take you to the first formula inserted in the topic.

4. Save. Mindomo re-renders the updated formulas automatically.

Frequently Asked Questions

Here are some frequently asked questions from Mindomo users about using math formulas.

1. Can I format math formulas for more clarity?

You can customize the math formula in the same way as regular text, including adjustments to font color, alignment, size or other formatting options.

Note

Formatting only works if the full formula is selected.

2. Can I add formulas from my mobile device?

Yes, Mindomo fully supports using math formulas on mobile devices, with no limitations.

3. How can I reuse formulas across diagrams?

Select the entire topic with the formula and copy it. Then, open a different map and paste the topic. The formula should be rendered correctly.

4. What should I do if the formula fails to render ?

If a formula fails to render, revisit the KaTeX code: check for missing backslashes, braces, or syntax errors.

5. Are there any best practices for using math formulas into a diagram?

• Keep formulas simple and readable - use KaTeX’s support for fractions, summations, integrals, etc., to keep formulas clean and professional.

• Combine KaTeX with text explanation - use comments or notes in the map to clarify complex steps.

• Preview and test your formulas - always preview your diagram to make sure KaTeX renders correctly on all devices and platforms. Sometimes formulas look different on mobile or in export formats (PDF, image).
