Linear format equations and Math AutoCorrect in Word

Applies To:Word 2016Outlook 2016Word 2013Outlook 2013Word 2010Word 2007

To insert an equation using the keyboard, press ALT+=, and then type the equation.

You can insert equation symbols outside a math region by using Math AutoCorrect. For more information, seeUse Math AutoCorrect rules outside of math regions check box.

Type equations in linear format

You can type most equations quickly by using Math AutoCorrect codes. For example, to align an equation array, you can use @ and &, as in the following:

eqarray(x+1&=2@1+2+3+y&=z@3/x&=6)<space>

which resolves to this:

Here are some other examples:

Example	Linear format	Built-up format
Vectors	(abc)vec<space><space>
	(abc)hat<space><space>
Boxed formula	ect(a/b)<space>
Brackets	(a+b/c)<space>
	{a+b/c}<space>
Brackets with separators	{a/bvbar<space>x+yvbar<space>}<space>
Fractions	a/(b+c)<space>
LeftSubSup	_a^b<space>x<space>
Limit	lim_(n->infty)<space>n
Matrix	(matrix(a&b@&c&d))<space>
Nary	iint_(a=0)^infty<space><space>a
Over/Underbar	overbar(abc)<space>
	overbrace(a+b)<space>
Radicals	sqrt(5&a^2)<space>

NOTE: When an example is followed by two consecutive spaces, the first space resolves the typed text into the equation, and the second space builds it up.

Microsoft Office uses the linear format described in Unicode Technical Note 28 to build up and display mathematical expressions. For more information, including how to quickly type up and build equations, seeUnicode Nearly Plain-Text Encoding of Mathematics.

Math AutoCorrect symbols

Type one of the following codes followed by a delimiting term. For example, after you type a code, type a punctuation mark, or press SPACEBAR or ENTER.

To ensure that the Math AutoCorrect symbols appear the same in your document as they do in the AutoCorrect dialog box, on theHometab, in theFontgroup, selectCambria Math.

IMPORTANT:The codes are case-sensitive.
