Formula input is very natural. Here are a few general rules: 'a^b' is automatically transformed to a b.If your exponential contains several terms, write 'a^(b + c)' which will be transformed to a b + c.If you really do want a (b + c), write 'a^((b + c))'. The same things apply to subscript: epsilon0, e.g. Using the Equation Editor Inserting an Equation To insert an equation, do one of the following. Word: Insert / Object / Microsoft Equation 3.0 WordPerfect: Insert / Equation If you are using Word on your home computer, you may want to add the equation editor to the toolbar so that it is much quicker to add equations.
Note: Office 2010 and 2007 offer built-in equationsupport; see Microsoft's explanations for Word2010 and Word2007.
In Office 2008 and 2004, Equation Editor is not always part of thetypical installation. To add Equation Editor, follow the appropriateinstructions below; you will need the installation CD or the files youdownloaded from IUware.
Note: In Office for Mac, the Equation Editor istypically installed by default. To check to see if it is installed,see the following path location, replacing version
with the version of Office you have installed:
If it is not installed already, to add Equation Editor:
Note: If you are installing a copy downloaded fromIUware, you should have a .dmg
file on yourdesktop. Usually, Mac OS X will automatically mount thisfile. If it doesn't, double-click the .dmg file to mount itand start the install process.

This book is about the Math Builder (officially called as Equation Editor) tool in Microsoft Word and Outlook 2007 and higher. It also applies to Microsoft PowerPoint and Excel 2010 and higher. Note that this is a different tool than the legacy tool Equation Editor 3.0 (which is still available on 32-bit Office versions until the January 2018 update[1]) and MathType.
Typesetting mathematics on a computer has always been a challenge. The mathematical community almost universally accepts a typesetting language called LaTeX. Math Builder is a much easier to use tool that has less functionality than LaTeX but more than typical document processing. Microsoft call this hybrid language the Office Math Markup Language, or OMML for short. It is an appropriate tool for:
Note that Math Builder does not perform any mathematics; it is a tool for displaying it.

Microsoft Word has two different typing environments: text and math. To obtain the math environment, click on 'Equation' on the 'Insert' ribbon on Windows or Word for Mac '16, or in 'Document Elements' on Word for Mac '11. The keyboard shortcut is 'alt'+ '='. For a Mac system, the shortcut is control + '='. Everything you type in this environment is considered math: all automatic formatting of text is disabled. To exit the math environment, click on any text outside the math environment. One easy way to do this is by pressing the right arrow key.
There are multiple ways to display a fraction. The default is vertically aligned as illustrated below. Obtain this by typing the fraction and pressing space: 1/2
Linear fraction (resp. skewed fraction) is obtained using ldiv (resp. sdiv) and pressing space (twice) or by typing 1 ldiv 2 (resp. 1 sdiv 2) and pressing space. While you can also do this by right-clicking on the equation and clicking Linear, this affects the whole equation and not just the fraction.
Grouping symbols will automatically size to the appropriate size. These symbols include '(), {}, [], ||'. For instance, the expression below can be obtained with (1/2(x+1)):
Be careful to press space after the '2' to render the fraction, otherwise Word might put 'x+1' in the denominator. Also press space after typing every closing parenthesis ')', which will adjust both the opening and closing parentheses size to fit the group's contents. Because the 1/2 fraction is is quite tall, the outer parentheses need to be adjusted to enclose the fraction appropriately. To be exact, the key presses required to reproduce the equation above are (

.
Exponents can be obtained by using '^' and subscripts by '_'. The monomial below can be obtained by typing x_2^5 or x^5_2 and pressing space.
These are all common symbols. The easiest thing to do would be to find a LaTeX reference sheet. A few of those symbols are shown here:
code | output |
neq or /= | |
leq or <= (resp. geq or >= ) | (resp ) |
subseteq | |
vee | |
rightarrow | |
Rightarrow | |
times | |
div | |
pm | |
infty | |
otimes (resp. oplus) | (resp. ) |
hbar | |
partial |
The math environment implements 3 fronts in addition to the default.
Blackboard bold letters can be obtained by typing ' followed by 'double' followed by the letter. doubled doubleD produces
A vector is often denoted by an overhead right arrow, which can be obtained by following a letter variable with 'vec': . Unit vectors (e.g. ) are denoted by a hat (circumflex), which can be obtained by following a letter variable with 'hat'. The gradient (also known as del or nabla) operator may be displayed using 'nabla'.
Dot notation for time derivatives (e.g. )can be obtained by following a letter variable with 'dot' for a first derivative and 'ddot' for a second derivative.
The dot product (inner product) can be displayed using the centered dot symbol 'cdot' e.g. the divergence . The cross product can be displayed using 'times' e.g. the curl .
Matrices are obtained with the 'matrix' symbol. Use parentheses to start and end the matrix. Use '@' to separate rows, and '&' to separate columns. The matrix below can be created by typing [matrix(1&2&3@4&5&6)]
.
Aligning equations can be obtained with the 'eqarray' symbol. Use parentheses to start and end the matrix. Use '@' to separate equations. Use '&' to specify alignment and whitespace. The first '&' and then every other occurrence is alignment. The second and then every other occurrence is white space. The equations below can be obtained by typing the following text:
(The math environment here seems to be adding excess space between the alignments that doesn't occur in Word)
Radicals are obtained using the 'sqrt' symbol, followed by the index, then '&', then the radicand.
For example: sqrt(a&b)
will output .
Additionally, sqrt(x)
will simply output .

Triple oriented integral (No corresponding Wikibooks math symbol) | |

Integrals are obtained by inserting the desired integral symbol (see above table), and then pressing space twice.[2]
For example: int_a^b

Equations have two forms. Inline specifies that the equation is to be in line with text. This affects a few expressions to make them appear smaller. For instance fractions will use a smaller font. Summations and integrals will place the endpoints to the right of the symbol instead of below it.Display specifies to use as much space as needed. Display mode equations must appear on their own line.
Everything in Math Builder requires special symbols that the computer knows how to interpret. These symbols are constructed with all the commands starting with ' as illustrated in the above sections. This is implemented via math autocorrect which you can modify. For instance, you might like to use ra instead of rightarrow. You can do this by adding the command to the math autocorrect directory.
