# Viewing Structure in MathML

MathML structure in a document can be viewed by choosing Show Structure from the Views menu. Choosing this option opens the Structure view, which reveals the main structure of the HTML document, the math tags, and their contents.

Math expressions can be edited in the main view or in the Structure view.

## Viewing Structure Example

The Structure view is especially helpful to avoid ambiguity. For example, in the equation below, placing the cursor after character, “b,” it is not clear whether you wish to add something within the square root or after it.

x=a+b+1

Selecting (or checking) in the Structure view avoids any misselections. You can also check the status line at the bottom of the main window.
