## 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.

## Insert a Square Root Symbol

#### Step

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.

## Type an Alt Code

By typing specific codes known as Alt Codes on your keypad, you can insert mathematical symbols into your Office documents.

#### Step

Press the **Alt** key and hold it down.

#### Step

Type **8730** on your keypad and release the **Alt** key. Word then inserts a radical sign in your document.
