What is LibreOffice Math?

* Software designed for creating and editing mathematical formulae.

* Bundled inside LibreOffice Suite, Open source, free of cost and free to distribute

* The formulae and equations created using Math can stand alone or used in LibreOffice Suite

* The formulae can be embedded into documents in Writer or Calc

* Examples of formulae are fractions, integrals, equations and matrices.
|What is LibreOffice Math?

LibreOffice Math is a software application designed for creating and editing mathematical formulae.

It is bundled inside LibreOffice Suite and hence it is open source, free of cost and free to distribute.

The formulae and equations created using Math can stand alone

Or can be used in other documents in the LibreOffice Suite.

The formulae can be embedded into documents in Writer or Calc.

Some examples of formulae are fractions, integrals, equations and matrices.

To Install LibreOffice Suite visit the official website: http://www.libreoffice.org
|For complete information on System requirements,
visit http://www.libreoffice.org/get-help/system-requirements/

If you have already installed Libreoffice Suite, then you will find Math in the LibreOffice Suite of programs.

If you have not installed LibreOffice Suite, then you can download it from the official website at http://www.libreoffice.org.

In linux you can install it from synaptic package manager.

I have installed LibreOffice Version 3.3.3
|-
|Click on Windows Start > All Programs >> LibreOffice Suite and Point on LibreOffice Math. (Do not click here.)

Point on Libreoffice Writer here. (Do not click.)

Click on Libreoffice Writer
|Okay, let us get started and open the Math application.
In Windows go to the Start menu. Click on All Programs>> LibreOffice Suite>> LibreOffice Math
Or we can call it from inside a LibreOffice Writer document.

Let us now click on LibreOffice Writer to open a new text document.
|-
|Click on the Insert menu on the top > Object >Formula.
|Now, in the Writer window, let us call Math.
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.
|-
|Move the mouse appropriately as narration goes forward.

Click View menu on top, point on Elements.

Click once outside the gray box in the Writer area, the Math windows disappear

Double click on the gray box

|Now we can see three areas in the Writer window.

The first is the Writer area on the top.

Here, notice the small gray box.

This is where the equations or the formulae we write will appear in the mathematical form.

The second is the Formula Editor area at the bottom.

Here we can type the mathematical formulae in a special markup language.

And the third is the Elements window that floats on the right.

If you don’t see the Elements window, we can access it by clicking on the View menu and then choosing Elements.

This window provides us with a range of mathematical symbols and expressions.

If we click once outside the gray box in the Writer area, the Math windows disappear.

Double click on the gray box to bring back the Math formula Editor and the Elements window.Double click on the gray box
|-
|Show mouse over appropriate areas as narration goes forward

In the Elements window,
click once on the top left icon and tool tip here says Unary or Binary Operators.

Point mouse over bottom half of Elements window.

Let us click on ‘axb’ on the second row. Show the tooltip.

Point mouse over the Formula editor window: <?> times <?>

Point mouse over Writer gray box area on the top

Double click on first <?> (also called place holder) in the Formula editor, then type 4.

Double click on second <?> (also called place holder) in the Formula editor, then type 3

Point mouse over Writer gray box area on the top

Click on View > Update.

Click on the second icon that says ‘Relations’ in the Categories section in the Elements window.

Point mouse over elements window bottom half.

Click on the first icon: ‘a=b’

Use Delete key to delete the first placeholder, then double click on the second place holder, and type 12

Point mouse over Writer gray box area on the top
|Let us click once on the top left icon. The tool tip here says Unary or Binary Operators.

And at the bottom, we see some basic mathematical operators such as plus, minus, multiplication and division.

Let us click on ‘a into b’ in the second row denoting multiplication.

Now notice the Formula editor window.

It shows two place holders separated by the word ‘Times’.

Also in the Writer gray box area at the top, notice two squares separated by the multiplication symbol.

Let us highlight the first placeholder in the Formula editor by double clicking it and then typing 4.

Next, let us highlight the second place holder and type 3 in the Formula editor window.

Notice that the Writer gray box has refreshed automatically and it displays ‘4 into 3’.

We can also click on the View menu at the top and choose Update.

Or use the keyboard shortcut F9 to refresh the window.

Next let us complete the formula and add ‘is equal to12’ to it.

For this, let us click on the second icon that says ‘Relations’ in the Categories section in the Elements window.

Notice the various relation elements here.

Let us select the first one: ‘a is equal to b’

And we will delete the first placeholder and type 12 in the second place holder.

And there is our first simple formula in the Writer area. ‘4 times 3 is equal to 12’.

Three ways of entering a formula

1. Use symbols from the Elements window
2. Right click on Formula Editor and choose symbols from the context menu showing the categories
|Now we learnt how to use the Elements window to write a formula in a very easy way.

We can also write a formula by right clicking on the Formula Editor window and selecting symbols here.
|-
|Go back to Writer window.

Right click on the Formula Editor window.

The context menu shows the same categories of symbols. Mouse over to show symbols in each category. No need to click on symbols.
|The context menu displays the same categories of symbols as in the Elements window.

Choosing any category displays the available symbols in that category.
|-
|Show Slide Number 6 again
Three ways of entering a formula

1. Use symbols from the Elements window
2. Right click on Formula Editor and choose symbols from the context menu showing the categories
3. Type formulae directly in mark up language
Example of mark up language: 4 times 3 = 12, 4 over 4 = 1
|There is a third way of writing a formula.

We can directly write the formula in the Formula Editor window.

Here we will use a special mark up language that the Math application understands.

We already saw one simple example of the mark up language.

‘4 times 3 equals 12’.

Notice the word ‘times’ here.

Similarly to write 4 divided by 4 equals 1, the mark up is :
‘4 over 4 equals 1’.
|-
|Show Slide Number 7
Assignment:
In the Writer, write the following formulae

1. 4 / 4 = 1
2. Use ‘newline’ mark up to enter a blank line in between your formulae
3. a Boolean AND b
4. 4 greater than 3
5. x is approximately equal to y
6. 4 is not equal to 3
|Now that we are done, here is an assignment for you:

In the Writer window, write the following formulae

1. 4 divided by 4 = 1
2. Use ‘newline’ mark up to enter a blank line in between your formulae
3. a Boolean AND b
4. 4 is greater than 3
5. x is approximately equal to y and
6. 4 is not equal to 3
