Time	Narration
00:02	Welcome to the Spoken tutorial on LibreOffice Math.
00:06	In this tutorial, we will cover Introduction and Formula Editor of LibreOffice Math.
00:12	We will learn the following topics:
00:15	What is LibreOffice Math?
00:18	System requirements for using Math Using the Formula Editor
00:23	Writing a simple formula
00:26	What is LibreOffice Math?
00:29	LibreOffice Math is a software application designed for creating and editing mathematical formulae.
00:38	It is bundled inside LibreOffice Suite and hence it is open source, free of cost and free to distribute.
00:47	The formulae and equations created using Math can stand alone
00:53	Or it can be used in other documents in the LibreOffice Suite.
00:58	The formulae can be embedded into documents in Writer or Calc.
01:05	Some examples of formulae are fractions, integrals, equations and matrices.
01:13	Let us look at the System requirements for using Math.
01:17	For Windows, you will need Microsoft Windows 2000 (Service Pack 4 or higher), XP, Vista, or Windows 7;
01:28	Pentium-compatible PC 256 Mb RAM (512 Mb RAM recommended);
01:36	For Ubuntu Linux,the system requirements are: Linux kernel version 2.6.18 or higher; Pentium-compatible PC 512Mb RAM recommended
01:51	For complete information on System requirements,visit the libreoffice website.
01:58	If you have already installed Libreoffice Suite, then you will find Math in the LibreOffice Suite of programs.
02:06	If you have not installed LibreOffice Suite, then you can download it from the official website:
02:14	In linux you can install it from the synaptic package manager.
02:18	I have installed LibreOffice Version 3.3.3
02:24	Okay, let us get started and open the Math application.
02:28	In Windows go to the Start menu. Click on All Programs>> LibreOffice Suite>> LibreOffice Math
02:39	Or we can call it from inside a LibreOffice Writer document.
02:46	Let us now click on LibreOffice Writer to open a new text document.
02:53	Now, in the Writer window, let us call Math.
02:57	Let us click on the Insert menu on the main menu bar, and then Object which is toward the bottom and then click on Formula.
03:09	Now we can see three areas in the Writer window.
03:14	The first is the Writer area on the top.
03:18	Here, notice the small gray box.
03:22	This is where the equations or the formulae we write will appear in the mathematical form.
03:30	The second is the equation or the Formula Editor area at the bottom.
03:37	Here we can type the mathematical formulae in a special markup language.
03:44	And the third is the Elements window that floats on the right.
03:50	If you don’t see the Elements window, we can access it by clicking on the View menu and then choosing Elements.
04:01	This window provides us with a range of mathematical symbols and expressions.
04:08	If we click once outside the gray box in the Writer area, the Math windows disappear.
04:17	Double-click on the gray box to bring back the Math Formula Editor and the Elements window. Okey.. let us now write a simple multiplication formula: 4 multiplied by 3 is equal to 12.
04:37	Now the Elements window has categories of symbols on the top and symbols at the bottom.
04:46	Let us click once on the top left icon. The tool tip, here, says Unary or Binary Operators.
04:57	And at the bottom, we see some basic mathematical operators such as plus, minus, multiplication and division.
05:08	Let us click on ‘a into b’ in the second row denoting multiplication.
05:17	Now notice the Formula editor window.
05:20	It shows two place holders separated by the word ‘Times’.
05:27	Also, in the Writer gray box area at the top, notice two squares separated by the multiplication symbol.
05:37	Let us highlight the first placeholder in the Formula editor by double clicking it and then typing 4.
05:46	Next, let us highlight the second place holder and type 3 in the Formula editor window.
05:54	Notice that the Writer gray box has refreshed automatically and it displays ‘4 into 3’.
06:03	We can also click on the View menu at the top and choose Update.
06:10	Or, we can use the keyboard shortcut F9 to refresh the window.
06:16	Next let us complete the formula and add ‘is equal to 12’ to it.
06:24	For this, let us click on the second icon that says Relations in the Categories section in the Elements window.
06:35	Notice the various relation elements here.
06:38	Let us select the first one: ‘a is equal to b’.
06:44	And we will delete the first place holder and type 12 in the second place holder.
06:53	And there is our first simple formula in the Writer area. ‘4 times 3 is equal to 12’.
07:02	Now we learnt how to use the Elements window to write a formula in a very easy way.
07:09	We can also write a formula by right-clicking on the Formula Editor window and selecting symbols here.
07:19	The context menu displays the same categories of symbols as in the Elements window.
07:26	Choosing any category displays the available symbols in that category.
07:33	There is a third way of writing a formula.
07:37	We can directly write the formula in the Formula Editor window.
07:42	Here, we will use a special mark-up-language that the Math application can understand.
07:50	We already saw one simple example of the mark up language.
07:56	'4 times 3 equals 12’.
07:59	Notice the word ‘times’ here.
08:03	Similarly to write 4 divided by 4 equals 1, the mark up is : '4 over 4 equals 1’.
08:15	Now that we are done, here is an assignment for you:
08:20	In the Writer window, write the following formulae.
08:24	4 divided by 4 = 1.
08:29	Use ‘newline’ mark up to enter a blank line in between your formulae.
08:36	A Boolean AND b
08:40	4 is greater than 3
08:43	x is approximately equal to y.
08:47	And 4 is not equal to 3.
08:51	This brings us to the end of this tutorial on LibreOffice Math- Introduction and Formula Editor.
08:59	To summarize, we learned the following topics:
09:03	* What is LibreOffice Math?
09:06	* System requirements and prerequisites for using Math
09:10	* Using the Formula Editor
09:12	* Writing a simple formula.
