Visual Cue Narration
Title Slide Welcome to thisis Spoken tutorial on Introduction to LibreOffice Math.
Slide:

Learning Objectives

In this tutorial, we will learn about:
  • LibreOffice Math
  • System requirements and Prerequisites for using Math.
Slide:

Learning Objectives

We will also learn to:
  • Use Formula Editor to write the formulae.
  • Use the markup language to write a simple formula and
  • Save the file.


Slide:

What is LibreOffice Math?

What is LibreOffice Math?
  • It is a software application designed to create and edit mathematical formulae
  • It is bundled inside LibreOffice Suite, hence it is free and open source software.
Slide:

What is LibreOffice Math?

  • The formulae and equations created using Math can stand alone.
  • They can be embedded directly into Writer, Calc and Impress.


Slide:

OS and Versions

LibreOffice Math can run on any of the following operating systems:


  • Microsoft Windows 8 or higher versions
  • GNU/Linux OS and
  • Mac OSX


Slide:

System Requirements

This tutorial is recorded using,
  • Ubuntu Linux OS version 18.04 and
  • LibreOffice Suite version 6.3.5


Slide:

LibreOffice Installation

https://spoken-tutorial.org/

  • By default the latest Ubuntu Linux OS has LibreOffice Suite pre-installed in it.
  • To install a specific version, refer to the LibreOffice Installation series on this website.


Narration only Let us learn how to open the LibreOffice Math.
Click on Show Applications >> search bar type ‘Math’ >> Click on LibreOffice Math icon. In Ubuntu Linux OS, click the Show Applications icon at the bottom left corner.


In the search bar that appears type Math.


From the displayed list, click on the Libreoffice Math icon.

Click on Start menu >> search bar type Math >> Click on LibreOffice Math icon In Windows OS, click on the Start Menu icon located at the bottom left corner.


In the search bar next to it type Math.


From the displayed list, click on the LibreOffice Math icon.

Point to the open window Math document opens up with Untitled 1 document.


Click on Show Applications>>search bar type ‘Writer’ >> Click on LibreOffice Writer icon. Now, let us learn to call Math from the Writer document.


I have opened the LibreOffice Writer document.

Click on the Insert menu.


Navigate to Object.

Select Formula from the submenu.


Point to the Math interface.

Click on the Insert menu on the menu bar.


Navigate to Object.

From the submenu select the Formula option.

Math interface opens.

Click outside the gray box.


Double click on the gray box visible in the Writer window.

In the preview area, if we click outside the gray box, the Math window disappears.

To make it visible again, double click on the gray box in the Writer window.

Click on close (x)

In the Save Document? dialog box click on the Don't Save button.

Let us close the Writer document without saving.

In the Save Document? dialog box click on the Don't Save button.

Cursor in the Math interface. Let us now first familiarize ourselves with the LibreOffice Math window.
Point to the three areas in the window. In the Math window we can see three areas.
Point to the first area on the top of the window. The first is the preview area on the top.


The preview area, displays the equations and formulae in the mathematical form.

Go to the bottom of the window >> point to the second area. The second is the Formula Editor area at the bottom.

Here we type the mathematical formulae in a special markup language.

Go to the right of the window >> point to the third area.

Click on the View menu >> Elements.

Third is the Elements dock on the left.

This dock provides us with a range of mathematical symbols and expressions.


If you don’t see the Elements dock, click on View and then choose Elements.

Go to the top of the Elements window >> Point to drop-down named Category Selector.


Click on the drop-down >> Point to the other category option.


Point to the selected category in drop-down >> point to symbols below the drop-down.

On the top of the Elements window, there is a drop-down named Element categories.


This drop down shows a list of mathematical symbols and operators.


As per the selected category, Elements dock displays the symbols and operators.

Point to drop-down >> Unary or Binary Operators.


Point to the drop down.

Point to the respective symbols.

By default Unary or Binary Operators option is selected in the Element categories.

Below the drop-down, we see basic mathematical operators.


These include Addition, Subtraction, Multiplication, Division and others.

Cursor in the interface. Let’s now write a simple multiplication formula.


Click on the symbol ‘❒ x ❒’

Go to the Formula editor window-> Point to two ‘<?>’ and then ‘times’ .


Go to the Writer gray box area -> Point to two squares and then ‘X’.

Let us click on the symbol squarebox into squarebox denoting multiplication.


The Formula editor window, shows two placeholders separated by the word times.


The preview area, diaplays two squares separated by the multiplication sign.

Go to Formula editor window >> double click on first ‘<?>’ >> type 4.


Double click on second ‘<?>’ >> type 3.

Point to the preview area.

4X3

In the Formula editor, first placeholder is selected.

Type 4 in this placeholder.

Then double click on the second placeholder and type 3.

The preview area shows 4 times 3.

Point to the formula. Next let us complete the formula by adding = 12 to it.
Go to the Element window >> click on the drop-down -> select Relations.

Point to symbols below drop-down.

In the Elements dock, click the Element categories, drop-down and select Relations.


Below the drop-down, notice the various relation elements.

Click on the symbol ‘❒ = ❒’


Click the first symbol squarebox equal squarebox denoting Is Equal.
Go to the Formula editor window >> delete first ‘<?>’ >> double click on second ‘<?>’ >> type 12.


Point to the formula.


In the Formula editor window, delete the first placeholder.

In the second placeholder, type 12.


In the preview area we can see the formula.

‘4 times 3 equals 12’.

Cursor in the interface. Now, let’s learn how to write a formula in different ways.
Point to the symbols in the Elements dock. We already know how to use the symbols in the Elements dock.
Cursor in the Formula editor. The second method is to use the context menu in the Formula Editor window.
Right click on the Formula editor window >> Point to the categories in the context menu


Go to one the category >> Point to available symbols


Show the categories.

Right click in the Formula editor to see the context menu.


The context menu displays the same categories of symbols as in the Elements dock.


You can choose any category to see the available symbols under the category.

Only narration Third method is to directly write the formulae in the Formula Editor window.

We will use markup language that Math understands.

Only narration


Point towards the word ‘times’


We already saw one simple example of markup language.


Point to the formula editor.

Select the formula and press the Delete key on the Keyboard


Point to the preview area.

Let us delete the formula from the formula editor.


Select the formula and press the Delete key on the Keyboard.


Notice that the formula is deleted from the preview area also.

Type ‘4 over 4 equals 1’ Now let’s write the markup language for 4 divided by 4 equals 1,

In the Formula editor type ‘4 over 4 equals 1’.

Point to ‘4 over 4 equals 1’. We will learn more about the markup language in the upcoming tutorials.
Click on File and Select Save.


Point to the dialog box.

Type file name as firstmath

Let us now save the file.

Click on File and select Save.


Save dialog box appears.


I will save the file in my Documents folder.


Type the filename as firstmath and click on Save button.


File is saved with the .odf extension.

Narration only: With this we have come to the end of this spoken tutorial.


Let us summarize.
