Chapter 11: Using OpenOffice.org Math

The command dialogue box displays the commands that create the equation. The dialogue

box can be edited directly.

Creating an Equation with dialogue Commands

To create an equation with equation editor, enter the programming commands in logical

sequence into the dialogue box. The commands entered are similar to the commands used to

generate equations in TeX ( a scientific publishing format).

Maintaining logical consistency of the commands entered into the dialogue box is important.

The brackets used in the dialogue box must be matched, for example all "(" must have a

corresponding ")".

Here are some examples. As can be seen, it is really simple to type formulae in the dialogue

box.

Command Input Field Formula

1+1=2

11= 2

The next example shows how round brackets ( ) and braces { } are used. The parenthesis are

used when it is desired to display grouping in the equation, the brace is used to group the

commands, but to not display. If braces are needed in an equation, then the lbrace and rbrace

commands are used.

Command Input Field Formula

(1+2) over (2+3)

1 2

 2 3

{ 1+2 } over { 2+3 }

1 2

2 3

lbrace 1+2 rbrace over lbrace 2+3 rbrace

{12}

{2 3}

Here is a more complicated example.

Command Input Field Formula

{{1 over 5} +4} over {5+{4+1}over{3+3+1}}

 4

5

41

3 31
