Stop Text Wrap in Word 2010 for an Equation Object

Solution 1:

While Dominik's answer will work just fine, it will add a space in your equation next to the mathematical operator, which you will likely not want.

The way around it is to use the No-Width No Break special character. To do so:

• Go to where you want the equation not to break. This is typically immediately after an operator (=,+,-,etc).
• Click on insert → Symbols → More Symbols
• Pick the "Special Characters" tab
• Scroll to the bottom and insert the "No-Width Non Break" character

You can also add a shortcut key for it to simplify this process

Solution 2:

Word (2010) wraps long equations (in display format) only before some mathematical operators, like =, +, ∈ etc. (I know this from testing.)

To avoid the wrap, you can use a nonbreaking-space Ctrl+Shift+Space directly before the operator.
