||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
