Equation Editor

The Equation Editor allows you to create complex mathematical equations, matrices, and expressions directly on the whiteboard.

It supports a wide variety of mathematical symbols, operators, and formatting options, providing you with a versatile tool for all your mathematical needs.

Creating an equation

To activate the Equation Editor, click the Formula button in the toolbar, or press G on your keyboard.

Then, click anywhere on the board to start creating an equation. This will open the formula toolbar, where you can access a wide range of mathematical symbols and formatting options to construct your equation.

Inserting mathematical symbols and notations

You can insert basic numbers, letters, and commonly used symbols directly using your keyboard. For mathematical symbols and operators that aren't available on the keyboard, select them from the toolbar. Symbols are organized into categories for easy navigation, making it simple to find what you need.

Many common mathematical notations can be typed directly into the editor using these shortcuts:

  • Type / to create a fraction.
  • Use ^ for exponents (e.g., typing x^2 will result in x²).
  • Type _ for subscripts (e.g., typing x_1 will display as x₁).

Press Enter to wrap to a new line within your equation.

Creating matrices and advanced structures

To insert a matrix or other advanced mathematical structures, select the appropriate icon from the toolbar. A template will appear that you can fill with your desired values.

For example, to create a 3x3 matrix, select the matrix icon, and a grid will appear where you can input each element.

You can also create custom-sized matrices quickly using keyboard commands. For instance, typing \m[4,3] followed by a Space will create a matrix with 4 columns and 3 rows, allowing you to customize it as needed.

To insert more complex structures, such as integrals, summations, or Greek letters, use the toolbar. Hovering over each symbol displays a tooltip with a LaTeX-like command that can also be entered directly from your keyboard.

Formatting equations

You can customize the appearance of your equations by adjusting stroke style, fill color, font size and color.

The default alignment option arranges equations on different lines by their equal signs or similar operators, ensuring a neat, structured layout. If you prefer simpler alignment, you can align equations to the left, center, or right regardless of content. You can easily save any of these alignment options as your default for future use.

Additionally, you can select and save a default font size, letting you keep your equations consistent and easy to read.

Editing and moving equations

To edit an existing equation, double-click on it to reopen the Equation Editor. You can then make any necessary changes.

To select a specific part of an equation, click and drag your mouse over the desired section. You can then copy (Ctrl + C) or paste (Ctrl + V) the selected part, or replace it with new content.

To move an equation around the whiteboard, click and drag it to your desired location. Use the green handles around the equation's border to resize it as needed.
