Linear format equations using UnicodeMath and LaTeX in Word

Linear format is a representation of math on one line in documents. There are two linear formats for math that Word supports:.

• Unicode math

• LaTeX math

Depending on your preferred input format, you can create equations in Word in either one of UnicodeMath or LaTeX formats by selecting the format from the Equations tab. 

To create a fraction using these different formats with subscript,

• Enter your equation using Alt + = on the keyboard.

• Choose Convert and select professional to build your typed fractions to their Professional form into subscripts, or use Ctrl + =. You can similarly convert an equation back down to a linear format with Ctrl + Shift + =. 

  

Examples

UnicodeMath resembles real mathematical notation the most in comparison to all of the math linear formats, and it is the most concise linear format, though some may prefer editing in the LaTeX input over UnicodeMath since that is widely used in academia. 

You can type most equations in UnicodeMath 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:

Here are some other examples:

Example	UnicodeMath format	Built-up format
Vectors	(abc)\vec<space><space>
	(abc)\hat<space><space>
Boxed formula	\rect(a/b)<space>
Brackets	(a+b/c)<space>
	{a+b/c}<space>
Brackets with separators	{a/b\vbar<space>x+y\vbar<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>

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, see Unicode Nearly Plain-Text Encoding of Mathematics.

LaTeX equation editing supports most of the common LaTeX mathematical keywords. To create a 3x3 matrix equation in the LaTeX format, type the following into a math zone:

A=\{\matrix{a&b&c\\d&e&f\\g&h&j}\}

This will build into the following professional equation:

Here are some other examples of LaTeX expressions that can be built-up into a professional format.

Most LaTeX expressions are supported in this new feature to Word; a list of exceptions is provided below for LaTeX keywords that are not currently supported.

Some LaTeX expressions take a slightly different syntax than might be expected.

For example, LaTeX matrices are often created using the following syntax: 

\begin{matrix} a & b \\ c & d \end{matrix}

However \begin{} and \end{} keywords are not supported in Word, so instead, a LaTeX matrix input takes simply \matrix{} and would look like:

\matrix{a & b \\ c & d}

Office has Math AutoCorrect that can be used to make UnicodeMath format simpler by automatically recognizing expressions and symbols as they are input and converting them to a professional format as the equation is created. This setting can be enabled or disabled by checking the appropriate box in the Equation Options dialog. 

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 the Home tab, in the Font group, select Cambria Math.
