||Welcome to the Spoken tutorial on LibreOffice Math.

||Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing

||In the last tutorial, we introduced the mark up language for Math.  

||Now let us learn more about Mark up language.

||Let first open a Writer document and then call the Math application inside Writer.

||If Writer is already open, then click on the Insert menu at the top and then click on Object and  choose Formula.

||If Writer is not  open, we can invoke it from the Windows Start menu.

||Using the Elements window is a very easy method of writing a formula.

||But directly writing the mark up language in the Formula Editor is a faster way of writing a formula

||Because markup language for a formula resembles the way we would read the formula in English.

||For example, to write ‘4 into 3’, , we just need to type in the Formula Editor window ‘4 times 3’

||Simply type the markup ‘newline’ and notice that a new line is inserted in the Writer gray box area.

||Let us type ‘Some more example formulae: newline’.  

||For readability we will press the Enter key once.

 

||And write ‘x greater than equal to y’.  

||So we will type ‘1. x greater than equal to y new line’. Press enter

||Notice the Writer gray box has refreshed and the contents are centered.

||Next let us write: ‘a to the power of 10’.  

||And the markup is: ‘2. 'a' arrow pointing upward 10’  new line’ and press Enter

||Notice the mathematical symbol in the Writer gray box.

||Now let us write ‘square root of 16 = 4’

||Type ‘3. sqrt   ‘16’ within curly brackets equals 4 new line’. Press Enter

||Notice this formula in the Writer gray box.

||And the markup is:, ‘4. sum a underscore n  new line’. Press Enter.

||Now let us try an integral with a function. To write Integral f x d x, the markup is,‘5. int fx dx newline’.

||And notice the integral symbol in the Writer area.

||Let us save our work now.  Go to File menu at the top, click on Save.

||Name the document as MathExample1.

||Now let us learn how to format the formulae we wrote .

||We can use the Format menu at the top for making various format changes.

||For this, let us click on Format menu and choose Alignment.

||In the new window, choose the Left option. And click on the Ok button.

||We can change the font style by choosing ‘Fonts’ under the Format menu.

||Notice the various categories here:

||To modify the font style, click on the Modify button and choose the category Variables.

||Let us choose Arial Black in the list box and click on the Ok button.

||And let us save the font, by clicking on the Ok button here.

||Now notice the font changes in the Writer gray box.

||To increase the font size of the formulae, go to Format menu and click on Font Size .

||Let us increase the Base size to ‘18 point’. Click on OK.

||We can change the relative sizes of other categories such as the text or indexes or operators.

||We can also use the Default button to undo all the font size changes we made.

||Notice the font size changes in the formulae.

||click on Format menu and choose Spacing.

||Let us change the spacing, line spacing and root spacing each to 20 percent.

||As we click on each spacing type, the image in the centre shows the location of the spacing type.

||Again we can choose spacing types from the various categories. To do this, let us click on the Category button

||Or use the Default button to undo our changes.

||Let us click on the Ok button now.

||And notice the spacing changes in the Writer gray box.

||More formatting is available in the Elements window.

||Let us bring up the Elements window from the View menu.

||Here, let us click on the last icon in the second row of categories.

||The tooltip here says ‘Formats’.

||Here, we can choose placements of subscripts and superscripts, alignments, matrix, new lines and gaps.

||Let us introduce a long gap in the fifth example, after the number 5 .Click after ‘5.’

||Then from the Elements window click on Formats> Long Gap  

||So these are the ways we can format our formulae.  

||Feel free to explore all the formatting options which Math provides.

||In the Writer window, write the following formulae using Mark up.  

||Use Elements window if necessary

||Summation of x to the power of 2

||Sin to the power of x plus cos to the power of x = 1 (use the Functions category in the Elements window)

||Continued from the previous slide Write Summation from 1 to n of x.  

||(use the Operators category to set the limits for summation)

||Change font to Arial and size to 18 point

||And Provide more spacing between the symbols.

||This brings us to the end of this tutorial on Mark up Language and Formula Formatting in LibreOffice Math

||Mark up language for writing formula and Formula formatting: Fonts, Alignment, and Spacing
