| 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. Ok.. 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. |
