1. There is a menu bar at the top of the computer screen.

Accessibility | Contact US | A-Z Index | Search | Notify | Stats | Edit | Sign in

2. First move your mouse to the Edit button and then a pull-down menu will appear.

• Edit centre content
• Edit right content
• Edit page properties
• Edit page permissions
• Create a new page
• Upload a file
• & more ...

3. Click on 'Edit centre content' in the menu. Then, you are in the Edit mode. You can write or delete words or sentences, just like an MS Word.

For example,

The Reynolds number is 180, or The Reynolds number is 180 395.

(You can see two rows of buttons, at the top right you can see B for Bold, I for Italic, stroke for delete, subscript and superscrips, you can use any of them when necessary).

4. At the top of the window, there are three buttons - Cancel, Preview & Publish. When you have finished, click on 'Preview' to see whether the changes are made correctly, or simply click on 'Publish'. The Cancel button is for when you made any mistake and you don't want that changes.

Hope it helps.
