When you insert a numbered MathType equation in Word, MathType uses Word's field codes to insert the number, but there's nothing in the field code itself that identifies an equation uniquely. For example, here are the field codes for equation number (1.1) in a document with 3 equations (1.1 through 1.3). In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used.

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:

• Typing any document whose focus is not itself mathematics.
• Typing a short math document quickly.
• A stepping stone between word processing (MS Word) and typesetting (LaTeX)

Note that Math Builder does not perform any mathematics; it is a tool for displaying it.

Pros and Cons[edit]

Pros:

Dot Product In Microsoft Word Equation Builder

• Math Builder is WYSIWYG: after typing an equation you see immediately what it looks like.
• It's easy to get started: it's already built in to Microsoft Word. Common symbols have point-and-click icons.
• It's easy to use: Common symbols have keyboard shortcuts so that a veteran user need not use a mouse at all.
• Nearly all symbols use the same commands as LaTeX.
• The format used is non-proprietary and given in Unicode Technical Note #28.
• It can be used in Outlook to easily write equations in emails; it renders as images to the recipent.

Cons:

• Some uncommon symbols are not listed in the menu and require knowing the keyboard shortcut. Typically this is the LaTeX code for the symbol.
• There are differences between Math Builder and LaTeX code: advanced functionality that requires more than just a symbol tend to follow the same flavor but have slightly different syntax. Math Builder code tends to be shorter than LaTeX code and disappears upon completion to the WYSIWYG output. Examples here are matrices, multiple aligned equations, and binomial coefficients.
• No LaTeX typesetting tools such as labels and references are implemented.
• No highly advanced LaTeX tools such as graphing, commutative diagrams, or geometric shapes are implemented. (Note:- Geometric shapes are otherwise available in the Insert ribbon)
• Students studying mathematics might not be motivated to learn LaTeX because they might be able to get by with Equation Builder in Word to satisfy the vast majority of their needs. However, when such a student reaches the limits, unlike LaTeX there is absolutely no recourse to expand the program to satisfy it.

Inserting an equation[edit]

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.

Common Mathematics[edit]

Fractions[edit]

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

Word Equation Dot Product

${\displaystyle \frac{1}{2}}$

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.

${\displaystyle v/p}$

Parenthesis, brackets, and braces[edit]

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)):

${\displaystyle \left(\frac{1}{2}(x+1)\right)}$

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 (1/2space(x+1)space)space.

Exponents and subscripts[edit]

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.

${\displaystyle x_2^5}$

Symbols: ${\displaystyle \ne ,\le ,\subseteq ,\vee ,\to ,\Rightarrow }$ etc[edit]

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:

Greek, Script, and Fraktur letters[edit]

The math environment implements 3 fronts in addition to the default.

• Greek letters can be obtained by typing a ' followed by the name of symbol. Capitalizing it creates a capital letter. delta Delta produces ${\displaystyle \delta \mathrm{\Delta }}$
• Script letters can be obtained by typing ' followed by 'script' followed by the letter. scriptd scriptD produces ${\displaystyle \mathcal{d}\mathcal{D}}$
• Fraktur letters can be obtained by typing ' followed by 'fraktur' followed by the letter. Fraktur does not have capitals. frakturd prodouces ${\displaystyle \mathfrak{d}}$

Blackboard Bold letters[edit]

Blackboard bold letters can be obtained by typing ' followed by 'double' followed by the letter. doubled doubleD produces ${\displaystyle \mathbb{d}\mathbb{D}}$

Mathematical Physics[edit]

Vectors[edit]

Three Dots In Microsoft Word

A vector is often denoted by an overhead right arrow, which can be obtained by following a letter variable with 'vec': ${\displaystyle \overrightarrow{A}}$. Unit vectors (e.g. ${\displaystyle \hat{x}}$) 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 ${\displaystyle \mathrm{\nabla }}$ may be displayed using 'nabla'.

Newtonian Dot Notation[edit]

Dot notation for time derivatives (e.g. ${\displaystyle \dot{r},\ddot{r}}$)can be obtained by following a letter variable with 'dot' for a first derivative and 'ddot' for a second derivative.

Vector Products[edit]

The dot product (inner product) can be displayed using the centered dot symbol 'cdot' e.g. the divergence ${\displaystyle \mathrm{\nabla }\cdot A}$. The cross product can be displayed using 'times' e.g. the curl ${\displaystyle \mathrm{\nabla }\times A}$.

Matrices[edit]

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)].

Multiple Aligned Equations[edit]

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[edit]

Radicals are obtained using the 'sqrt' symbol, followed by the index, then '&', then the radicand.

For example: sqrt(a&b) will output ${\displaystyle \sqrt[a]{b}}$.

Additionally, sqrt(x) will simply output ${\displaystyle \sqrt{x}}$.

Integrals[edit]

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

For example: int_a^bspacespace1/xspacedx will output ${\displaystyle \underset{a}{\overset{b}{\int }}\frac{1}{x}dx}$

Inline versus Display[edit]

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.

Modifying and creating shortcuts[edit]

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.

When editing some documents involving mathematical formulas and symbols in Word, it can be a challenge to input them because you may not be able to find the corresponding buttons on keyboard. So what’s the best way to insert these relatively difficult formulas? Here are 3 commonly used methods you can try.

Method 1. Insert Equations Symbols

1. Go to Insert tab and choose Equation in Symbols section.

2. There are some pre-set formulas for you to choose and edit.

3. You can also select Insert New Equation, of course.

4. It will insert a textbox in the document and enable the Equation Tools in Design tab, in where you can insert different kinds of mathematical symbols directly.

5. Just hit the symbols you want to insert and input the specific numbers in the corresponding positions of the textbox. In this way you can input any mathematical formula you want.

Method 2. Ink Equation

If you don’t want to find these symbols separately and rather input the formula by handwriting, you can try the Ink Equation feature in Word 2016 and above versions.

1. Just switch to Insert tab and click Equation – Insert New Equation to toggle on Equation Tools. Then find Ink Equation button at the left side of the Equation Tools (Design) tab to invoke the handwriting window.

2. You can click Write button and use your mouse or writing pad to write the formula here. The identified formula will show at the top.

3. If there’s anything wrong, you can click the Select and Correct button and then hit the wrong part to choose the right symbol in the expanded menu.

4. You can also click Erase button to wipe part of the formula, or click Clear button to delete all the inks in the writing box.

5. After finishing the handwriting, just hit Insert to add the formula to your document.

Method 3. Microsoft Equation

1. Go to Insert tab, click Object button in Text section. Choose Microsoft Equation 3.0 in the list of Object type in Create New tab and click OK to confirm it.

2. Then the Equation toolbar will pop out along with a textbox. You can insert any mathematical symbol you want by clicking them in the toolbar. In this way you can also insert a difficult mathematical symbol quickly.
