Guide: how to write equations online

1. Build your first equation

1. Open the editor

   Click Open the editor. You see a white area with a toolbar above it.

2. Click a structure on the toolbar

   For example the fraction button. A fraction appears in your equation with two empty boxes.

3. Type into the boxes

   Type with your keyboard. Move between the boxes with the arrow keys or by clicking.

4. Add more

   Add a root, a power or a matrix from the toolbar. If you make a mistake, press Ctrl + Z to undo.

2. Type in Arabic

The easiest way is to open the Arabic version of the editor: the interface is Arabic and writing is right to left from the start.

If you are in the English editor, use the numbered buttons of the General tab:

1. Right to left editing so the equation grows from the right.
2. Arabic ligature so the Arabic letters you type connect into a word. Leave it off if your letters are separate variables.
3. Insert special characters, then Arabic math letters, to insert Arabic mathematical letters and derivative marks.

3. Download your equation as an image

1. Open the PNG tab

   Under the editor there is a row of tabs; click “PNG”.

2. Click Download

   The image is saved to your device with a white background.

3. Paste it where you need it

   In Word, Google Docs, PowerPoint or a web page.

4. Move a symbol exactly

Select the letter or mark by clicking and dragging over it, or with Shift + the arrow keys. Then open the contextual tab (the last tab) and click the four arrows to move it one pixel per click.
