Math is Apache OpenOffice’s component for mathematical equations. It is most commonly used as an equation editor for text documents, but it can also be used with other types of documents or stand-alone. When used inside Writer, the equation is treated as an object inside the text document. Similarly, one can also insert these into other Apache OpenOffice programs like Calc and Impress.

Math Equation Writer For Word
Using Math, there are three main ways of entering a formula:
Type markup in the equation editor.
Right-click on the equation editor and select the symbol from the context menu.
Select a symbol from the Elements toolbox.
What is an Equation?
An equation says that two things are equal. It will have an equals sign '=' like this:
x
+
2
=
6
That equations says: what is on the left (x + 2) is equal to what is on the right (6)
So an equation is like a statement 'this equals that'
(Note: this equation has the solution x=4, read how to solve equations.
What is a Formula?
A formula is a fact or rule that uses mathematical symbols. It will usually have:
an equals sign (=)
two or more variables (x, y, etc) that stand in for values we don't know yet
It shows us how things are related to each other.
Example: The formula for finding the volume of a box is:
V = lwh
V stands for volume, l for length, w for width, and h for height.
When l=10, w=4, and h=5, then:
V = 10 × 4 × 5 = 200
These are all equations, but only some are formulas:
x = 2y - 7
Formula (relating x and y)
a2 + b2 = c2
Formula (relating a, b and c)
x/2 + 7 = 0
Not a Formula (just an equation)
Without the Equals
Sometimes a formula is written without the '=':
Example: The formula for the volume of a box is:
lwh
But in a way the '=' is still there, because we can write V = lwh if we want to.
Subject of a Formula
The 'subject' of a formula is the single variable (usually on the left of the '=') that everything else is equal to.
Example: in the formula
s = ut + ½ at2
's' is the subject of the formula
Changing the Subject
A very powerful thing that Algebra can do is to 'rearrange' a formula so that another variable is the subject.
Example: Rearrange the volume of a box formula (V = lwh) so that the width is the subject
divide both sides by h:V/h = lw

swap sides:w = V/(hl)
So if we want a box with a volume of 12, a length of 2, and a height of 2, we can calculate its width:
