When you prepare slides
for an engineering
course, you need to
display mathematic
formulae.
This course will tell you
how to type such
formulae in PowerPoint.

Add formulae


Course goal
• Put a formula in you presentation.
• Navigate and edit a formula.
• Create a simple formula on a single line or a
complex multi-lines formula.

Add formulae


Lesson 1
Simple formulae


Insert a formula
Use the Insert menu to add a
formula to your PowerPoint
presentation.

1. Click on the Insert
menu and select
Object.

Inserting a formula via the
Insert menu.

2. Select Microsoft
Equation and click OK.

Add formulae


Enter the Equation Editor
The window that opens
has some symbols at the
top and a large equation
space at the bottom.
You type the equation by
selecting symbols from
the menus at the top and
typing other characters
on the keyboard.
The Equation Editor.

The equation goes into
the dash box.
Add formulae


Your first equation
On the keyboard you type
the characters: m, =, 3, x,
- and 7.
Notice how the equation
editor adds some space
around the equal sign and
minus sign.
A simple equation.

The Equation Editor tries
to follow the typographic
rules for presenting
mathematics.
Add formulae


You are done
When you are done with
typing your equation, you
exit the Equation Editor
and return to the
PowerPoint presentation.
1. Click on the File
menu.
Exit the equation editor.

2. Select Exit and
Return to
Presentation.

PowerPoint and the Equations
It does not look too good.

m = 3x − 7

Equations do not
integrate well with
PowerPoint: they are not
part of the text, they are
a separate object.
Size is too big, color is
wrong.
You need to fix this.
Add formulae


You need to change the color.
The equation appears
with a default color black,
this is probably not the
color used for your
presentation.
1. With the mouse, Right
Click on the equation.
Edit the equation color.

2. Select Show Picture
Toolbar.

Add formulae


Use the Recolor Picture tool.
On the Show Picture
Toolbar, use the

Recolor Picture tool.
The Recolor Picture
tool is started when you
click on the icon

Use Recolor Picture.

Add formulae


Use the Recolor Picture tool.
In the Recolor Picture
tool select the new color
you want to apply: for
example change black
into white.
Click OK when you are
done.
Use Recolor Picture.

Add formulae


Resize and move the equation
The equation is of the
right color.

m = 3x − 7

Use the round handles

to move and resize the
equation like any object
in PowerPoint.

Add formulae


Resize and move the equation
Adjust the size of the equation to be close to
the size of the text.
If the equations stands alone on a line, it
should be centered.

m = 3x − 7
You can also use the arrows to adjust the position of
the equation.

Add formulae


Add symbols to the equation.
The top line in the menu of
the Equation Editors give
access to some symbols like
Greek letters and others.

To add a σ click on the
menu
that
represents Greek letters

and select the character σ.
Use Greek letters and other
symbols.

Add formulae


Modify a symbol.
The menu
is special:
it does not add a symbol,
but it modifies the symbol
just before the cursor.

1. Position the cursor
(blinking bar) just after
the symbol you want
to modify.
Add a modifier to a symbol.

2. Select the modifier
from the menu
.

Add formulae


Type a function.
Mathematic symbols are
type in italics like x.

Name of a function are
typed in Roman like
Cos(x) or Factoriel(2).

Function names are in
Roman.

The Equation Editor
knows how to type Cos,
but you need to modify
Factoriel by yourself.

Add formulae


Type a function.
To type Factoriel in Roman:
1.Highlight the word Factoriel.

2. Click on the Style menu.

3. Select the option Text.

Function names are in
Roman.

Add formulae


Suggestion for practice

Prepare one page presentation and type the
following equations:

x = 3y
Cos(0) = 1
lim f ( x) x  ± ∞= 0
∀( x ∈ E ) x ≥ 2

Lesson 2
Complex formulae


Complex formulae
Not all formula can fit on
a single line. Mathematics
need superscripts,
subscripts, array of values
for a matrix, etc.
The second line of menu
give access to complex
symbols.
A complex formula.

Their size varies with the
equation.
