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, see Use Math AutoCorrect rules outside of math regions check box.

You can also create math equations using on the keyboard using a combination of keywords and math autocorrect codes. New to Word for Microsoft 365 subscribers is the ability to type math using the LaTeX syntax; details described below.

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. 

Image of the Design tab showing the equation formats available for LaTex format.

Note: All the other Office applications support only UnicodeMath linear format.

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

Create Fractions in Linear

Note: Convert a professional format equation format to it's source format, change the convert tool to build a linear format by selecting the desired option from the Convert menu.

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:

\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, 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:

Image showing an example of LaTex editing

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

Table showing LaTeX Equation examples

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.

Table showing unsupported LaTeX equation format

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. 

Image showing the Equation Options dialog box

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.

Important: The codes are case-sensitive.
