Add a square root symbol — also known as a radical sign — to a Microsoft Word document by using the program's AutoCorrect feature, inserting a symbol or typing an Alt code.

## Type an AutoCorrect Keyword

Word, like all other Microsoft Office programs, comes with a spell checker called AutoCorrect. In addition to checking for typos, AutoCorrect can also turn a series of predefined keywords into math symbols. For example, insert a square root symbol in Word by typing **\sqrt** in the document, followed by a space. Upon pressing the space bar, Word automatically turns \sqrt into a square root symbol.

Open the **Insert** tab and click the **Symbol** button. Select **More Symbols**.

#### Step

Select **Mathematical Operators** from the Subset drop-down menu and double-click the **radical sign** in the list of available symbols to insert it in your document.
