Time	Narration
00:00	Welcome to the Spoken tutorial on LibreOffice Math.
00:04	In this tutorial, we will cover the following topics:
00:08	Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing
00:18	In the last tutorial, we introduced the mark up language for Math.
00:24	Now let us learn more about Mark up language.
00:28	Let first open a Writer document and then call the Math application inside Writer.
00:35	If Writer is already open, then click on the Insert menu at the top and then click on Object and choose Formula.
00:46	If Writer is not open, we can invoke it from the Windows Start menu.
00:55	Using the Elements window is a very easy method of writing a formula.
01:01	But directly writing the mark up language in the Formula Editor is a faster way of writing a formula
01:10	Because markup language for a formula resembles the way we would read the formula in English.
01:18	For example, to write ‘4 into 3’, , we just need to type in the Formula Editor window ‘4 times 3’
01:28	Before we go to the next example, let us insert a blank line here.
01:36	Simply type the markup ‘newline’ and notice that a new line is inserted in the Writer gray box area.
01:46	Let us type ‘Some more example formulae: newline’.
01:52	For readability we will press the Enter key once.
01:57	And write ‘x greater than equal to y’.
02:03	Here we will also number the formulae.
02:07	So we will type ‘1. x greater than equal to y new line’. Press enter
02:18	Notice the Writer gray box has refreshed and the contents are centered.
02:25	Next let us write: ‘a to the power of 10’.
02:30	And the markup is: ‘2. 'a' arrow pointing upward 10’ new line’ and press Enter
02:42	Notice the mathematical symbol in the Writer gray box.
02:48	Now let us write ‘square root of 16 = 4’
02:55	Type ‘3. sqrt ‘16’ within curly brackets equals 4 new line’. Press Enter
03:06	Notice this formula in the Writer gray box.
03:10	Alright, now let us write a summation symbol for ‘a suffix n’, to denote a1 + a2 + a3 so on + ‘an’.
03:28	And the markup is:, ‘4. sum a underscore n new line’. Press Enter.
03:37	Now let us try an integral with a function. To write Integral f x d x, the markup is,‘5. int fx dx newline’.
03:54	And notice the integral symbol in the Writer area.
04:00	Let us save our work now. Go to File menu at the top, click on Save.
04:09	Name the document as MathExample1.
04:15	Now let us learn how to format the formulae we wrote .
04:21	Notice that they are all centered and don’t have a lot of space in between them.
04:28	We can use the Format menu at the top for making various format changes.
04:35	Let us first align all the formulae to the left.
04:40	For this, let us click on Format menu and choose Alignment.
04:46	In the new window, choose the Left option. And click on the Ok button.
04:54	Notice that the formulae are left aligned now.
04:58	We can change the font style by choosing ‘Fonts’ under the Format menu.
05:06	Notice the various categories here:
05:10	We can set one type of font for variables, another type for functions, another for numbers and text.
05:23	To modify the font style, click on the Modify button and choose the category Variables.
05:34	Let us choose Arial Black in the list box and click on the Ok button.
05:43	And let us save the font, by clicking on the Ok button here.
05:50	Now notice the font changes in the Writer gray box.
05:56	To increase the font size of the formulae, go to Format menu and click on Font Size .
06:06	Let us increase the Base size to ‘18 point’. Click on OK.
06:16	We can change the relative sizes of other categories such as the text or indexes or operators.
06:25	We can also use the Default button to undo all the font size changes we made.
06:32	Notice the font size changes in the formulae.
06:37	Next, let us make changes to the spacing of the formulae.
06:42	click on Format menu and choose Spacing.
06:48	Let us change the spacing, line spacing and root spacing each to 20 percent.
06:56	As we click on each spacing type, the image in the centre shows the location of the spacing type.
07:05	Again we can choose spacing types from the various categories. To do this, let us click on the Category button
07:16	Or use the Default button to undo our changes.
07:22	Let us click on the Ok button now.
07:25	And notice the spacing changes in the Writer gray box.
07:30	More formatting is available in the Elements window.
07:35	Let us bring up the Elements window from the View menu.
07:40	Here, let us click on the last icon in the second row of categories.
07:47	The tooltip here says ‘Formats’.
07:51	Here, we can choose placements of subscripts and superscripts, alignments, matrix, new lines and gaps.
08:03	Let us introduce a long gap in the fifth example, after the number 5 .Click after ‘5.’
08:13	Then from the Elements window click on Formats> Long Gap
08:20	The mark up for long gap is the ‘tilde’ character. And for the short gap, it is ‘Tiray’ character.
08:29	Notice the new gap after the number 5.
08:33	So these are the ways we can format our formulae.
08:38	Feel free to explore all the formatting options which Math provides.
08:44	Okay, here is an assignment for you:
08:47	In the Writer window, write the following formulae using Mark up.
08:53	Use Elements window if necessary
08:57	Summation of x to the power of 2
09:02	Sin to the power of x plus cos to the power of x = 1 (use the Functions category in the Elements window)
09:15	Continued from the previous slide Write Summation from 1 to n of x.
09:23	(use the Operators category to set the limits for summation)
09:29	Change font to Arial and size to 18 point
09:35	And Provide more spacing between the symbols.
09:40	This brings us to the end of this tutorial on Mark up Language and Formula Formatting in LibreOffice Math
09:49	To summarize, we learned the following topics:
09:52	Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing
