Tutorial for the Equation Editor in Microsoft
Office by Dr. Mojtaba Mirsalim
Though it is expensive, we chose Microsoft Office
because many of our students own the package
already and because it will be a valuable
addition to your software collection long after
the course is over, and because much of our
mathematical communication during the semester
will happen in power points and then in MATLAB.
2

• If you already have Microsoft Office on your
  computer, lets hope that Equation Editor has
  already been installed. Equations can be
  inserted into Word, PowerPoint, or any
  application that supports OLE (Object Linking and
  Embedding).
• Open a document in Microsoft Word
• Click on the menu item INSERT
• Towards the bottom of the list choose OBJECT
• Scroll through the list of objects looking for
  EQUATION EDITOR or for MICROSOFT EQUATION
• If you cannot find it, you will have to reinstall
  Microsoft Office. You can install Equation Editor
  through either custom installation or complete
  installation. A complete description about using
  the equation editor is available under Help in
  the equation editor window.

3

• To insert an equation, choose Insert, Object,
  Microsoft Equation 3.0, and click OK . One of 2
  things will happen
• A highlighted area will appear, along with
  equation editing palettes. This is known as
  in-place editing. It can be very difficult to see
  what is being entered. OR
• A separate window will open, with the
  palettes on top. This is much easier for entering
  equations. This looks like the following.

4

• To exit and return to your Word document you may
  choose File/Exit and Return to (Document Name)
  to update the Word document but remain in the
  equation editor you may choose File/Update.
• In-place editing is the default, but it is
  possible to have a separate window for EQUATION
  EDITING (remind me to talk about it later, next
  week).

5

• Once you have the Equation Editor installed, you
  can have an icon placed in your toolbar for easy
  access.
• Click View/Toolbars
• Select Customize/Commands
• Select Categories/Insert
• Under Commands, scroll down to Equation Editor
• Hold and drag the Equation Editor icon up to any
  existing toolbar/gray area that will accept it.
• You can do the same thing in Power Point.
• You are now ready to learn how to use your
  Equation Editor.

Your icon should look like this
6
When you double-click on the icon for the
Equation Editor, the window below should open up.
Each button on the menu bar gives you a sneak
preview to the many options that are available to
you when you click that button.
7
The buttons that you will use most frequently are
described below.
Grouping symbols with absolute value bars
Fraction and root icons
Greek letters including pi and theta
Exponents and subscripts
8
So, lets see if you can create the following
expression
Click on the Equation icon. You can create
exponents from the Equation menu bar but the
keyboard shortcut for exponents is Ctrl H. You
can remember this because H stands for high and
exponents are a little high. Type 3x followed by
Ctrl H. An icon should appear in the exponent
slot. Type 4 and then hit Tab to get out of the
exponent. Continue in this fashion until you are
done with the expression. When you are done click
on the document outside of the Equation Editor
work area and the expression that you created
will be inserted into your Word document. The
size can be adjusted by clicking on the equation
once and dragging the corners out to the
preferred size.

• Here are some other short cuts that will make
  your life easier
• Ctrl F for fractions,
• Ctrl R for square roots but for other roots
  use the tool bar,
• Ctrl L for subscripts,
• Ctrl ( or Ctrl ) for parentheses that
  grow with your expression.
• Use the Tab key to escape from each of the above
  modes.
• Ctrl space bar will create small spaces if
  you need them.
• Ctrl I for Definite Integral,
• Ctrl G for inserting Greek letters, followed
  by a letter key
• Ctrl Shift E for adding plain text
• Ctrl Shift for going back to math after
  adding text

10
Now see if you can create the following
expression before you move on to the next frame.
If you have not already done so, create a Word
document in which you can practice while you are
working with this tutorial.
11
Now lets see how you do with the Quadratic
Formula
You can find the plus-or-minus symbol in one of
the palettes in the menu bar.
12

• Type x
• Press Ctrl F for the fraction
• Type b

• Click on the palette that contains the
  plus-or-minus symbol in the menu bar
• Click on the plus-or-minus icon
• Press Ctrl R to create the root
• Type b and press Ctrl H
• Type 2 and press Tab
• Type 4ac and press Tab to escape the root
• Press Tab to enter the denominator and type 2a

13
Now, try to solve the following equation by
multiplying both sides of the fraction by the
12x(x 1).
14
With a construction this large, you should
probably copy it before you click out. You dont
want to lose it. Good luck.
15
Now, you are ready for the following assignments

The following time sequence r(kT) may be
determined from R(z) by use of the inversion
formula,
which is a contour integration along the path ?,
where ? is a circle of radius
centered at the origin in the z-plane, and c is
of such a value that all the poles of R(z) are
inside the circle.

Equation Editor Tips Tricks Here are some tips
and tricks for getting the most out of Equation
Editor. Except where indicated, these tips should
work for all versions of Equation Editor .
Editing equations in a separate window rather
than "in-place" Some Equation Editor users prefer
to have a separate window open each time they
create or edit an equation, rather than the
default "in-place" editing. There are several
possible reasons to prefer "open mode" editing
over in-place The viewing scale of the equation
windows can be controlled independently of the
viewing scale of the word processing or
presentation window. Whereas you might want to
edit your document at a scale of 100 or 125,
equations are sometimes hard to read and edit at
such scales. We recommend using 200 scale in
your equation windows. The menus and toolbars of
your word processor don't jump around when
switching back-and-forth between equation editing
and document editing. By opening Equation Editor
in a separate window, you can keep it open and
use it as an "equation scratchpad".
19
The easiest way to do this is to run Equation
Editor as a separate application. To make
this convenient, you need to find out where
Equation Editor is located on your computer's
hard disk and make a shortcut to it. Here's how
to do this Windows Use the Find Files or
Folders command on the Start menu to find a file
named EQNEDT32.EXE (or EQNEDIT.EXE on some
systems). Once you have found the file, make a
shortcut to it on your desktop or in the Start
menu. Consult your Windows documentation if you
don't know how to do this. The default location
is C\Program Files\Common Files\Microsoft Shared\
Equation.
20
Whenever you start working with equations, first
run Equation Editor by using the shortcut you
created. Equation Editor will open a new empty
equation window that is not associated with any
equation in any document. You can use this window
as a scratchpad, placing any equation or
expression in it that you want and using
cut-and-paste or copy-and-paste to transfer
expressions into the documents you create. Once
you have started Equation Editor this way, you
still insert new equations as you usually do.
Keep an Equation Editor window open to make
equations open faster (look at the next slide)
21
Formatting equations with numbers to the right
Display equations are equations that are placed
in their own paragraph, as opposed to "inline" or
"text" equations which are placed in the same
line as normal text. Although there are many ways
to format these, the most common is to center the
equation between the margins and insert an
equation number to the right of the equation,
flush against the right margin. This is easy to
do in most, if not all, word processors. The
basic idea is to place a centering tab-stop
centered between the left and right margins and a
right-justifying tab-stop placed exactly on the
right margin. For each equation, create a single
paragraph containing the following items from
left-to-right a tab, the equation, another tab,
the equation number. Here's what this looks like
in Microsoft Word (the tab-stops have been
circled in red)
22
Template "wrapping" and replacement Have you ever
typed an equation, then realized it would be
easier to read if this big expression were
enclosed in parentheses? Or, perhaps your
equation uses a summation template without
limits, then you decide it really must have
limits after all. Both of these situations can be
handled quickly without having to re-type the
equation or do a big cut-and-paste job. What you
need is template wrapping in the first case and
template replacement in the second. Template
wrapping Let's start with a common statistical
formula       
23
But now we notice a problem! The 1/n should apply
to the entire right side of the equation. Let's
indicate this by putting parentheses around it
and, because we want the parentheses to be big
enough to unambiguously enclose the expression,
we'll use a parenthesis template. Wrapping is
easy just select the part of the equation to be
wrapped
Now insert the wrapping template in the normal
way. An inserted template will wrap itself around
anything that is selected. So now our expression
looks like this
24
Template replacement Now we see another problem
the summation is supposed to have limits. To fix
this we'll use template replacement. First,
select the template and its contents
Next, hold down the Alt key (use the Option key
on the Macintosh). With the Alt key depressed,
press and hold the left mouse button until the
mouse pointer is over the template you want. When
the pointer is over that template, release the
mouse button, then release the Alt key. In this
case, we choose the summation with upper and
lower limits. All that is left is to type in the
limits and we are done
25
Putting a box around an equation
Often it's helpful to include an equation
enclosed inside a box, either for emphasis or to
set it apart from the surrounding data. This is a
great way to highlight the answer to an example
problem, such as
To do this, first create a 1-by-1 matrix. In the
matrix dialog box, click in the preview pane
outside the matrix on all four sides. This will
insert solid lines around the matrix. If you want
the lines to be dashed, click twice. If you want
them dotted, click three times. Click once more
to remove a line.
26
Use matrices to create simple blank grids
Equation Editor's matrix templates can be used
for all kinds of things. For example, here is a
blank grid that could be useful in a test or a
quiz calling for students to graph a function
To create such a grid, you just insert a matrix
with the appropriate number of rows and columns
and add partition lines between the elements.
These lines can be solid (click once between rows
or columns), dotted (click twice), or dashed
(click 3 times).
27
Animated equations in PowerPoint
you can use Equation Editor with PowerPoint to
create presentations containing equations. Here
we'll show you an additional technique. Insert
your equation into PowerPoint as described above.
Right-click on the equation, and from the menu
select Grouping/Ungroup. A dialog will appear
with a warning about the action youre about to
do. Click Yes. Your equation will then appear as
individual characters and templates, which you
can animate individually using SlideShow/CustomAni
mation.
28
To change the color of an equation inserted into
PowerPoint
Although most equations you create will be black
text on a white background, very often slide
presentations are created with colored text on a
dark or black background. Although Equation
Editor cannot create colored equations,
PowerPoint gives you the ability to change the
black and white of your equations to whatever
background color and foreground color you
want. Here's how to color an equation
29
1) Insert the equation into the slide the usual
way using Insert Object.
2) Right-click the equation object to bring up a
menu of commands.
3) Click on "Format Object", the last item on
the menu. This will bring up a dialog.
4) Click the tab titled "Picture". Under the
Picture tab, click "Recolor". When the "Recolor
Picture" dialog appears, you can change the
color. There should be black and white rectangles
in the "Original" section. Here you can change
both the white background and the black text
color, or either of them individually. Click the
dropdown box next to the black color in the "New"
column you can select any color shown there. You
can preview your selection to see if the color is
what you had in mind. If it looks fine, click OK
on both dialogs.
