=== Introduction ===
LibreOffice Writer is a free and open-source Formula Editing application of the LibreOffice software package. Math can be invoked in your text documents, spreadsheets, presentations and drawings, enabling you to insert perfectly formatted mathematical and scientific formulas. Your formulas can include a wide range of elements, from fractions, terms with exponents and indices, integrals, and mathematical functions, to inequalities, systems of equations, and matrices.
LibreOffice Math ('Math' hereafter) is a free and open-source formula editing application of the LibreOffice software package. Math can be invoked in your text documents, spreadsheets, presentations and drawings, enabling you to insert well formatted mathematical and scientific formulas. Your formulas can include a wide range of elements, from fractions, terms with exponents and indices, integrals, and mathematical functions, to inequalities, systems of equations, and matrices.
You can start Math either as a stand-alone application directly from the LibreOffice Start Center or directly from within other LibreOffice applications such as Writer, Calc, Impress and Draw.

====Overview of features====
LibreOffice Math lets you type and format mathematical formulae that can include signs and symbols. In this application you can save the documents in a variety of formats, including the standardized Open Document Format (ODF) or MathML Format (mml). Here you can easily export your document to the Portable Document Format(PDF).

Using the Formula Editor, you can create a formula as a separate document or file for a formula library, or insert formulas directly into a document using LibreOffice Writer, Calc, Impress, or Draw.
Using the Formula Editor, you can insert formulas directly into a document using LibreOffice Writer, Calc, Impress, or Draw.
==== Formulas in LibreOffice documents ====
LibreOffice Writer includes insertion of mathematical expressions in documents. A special feature. LibreOffice Math is an application that assists in insertion of mathematic or scientific formulas of a wide range is a part of LibreOffice writer.
LibreOffice Writer treats formulae as objects. For insertion of an expression at any point in the document go to '''Insert (in menu bar) → Object → Formula.'''
The Formula Window appears on the left hand-side, it has a variety of operations, functions and attributes that can be included in the document. The top drop down menu helps us toggle between different operations. Selecting the operations from the drop down box displays all the mathematical notations under each category. Clicking on the required mathematical notation inserts the notation in the document.
To edit this object or to insert numbers and variables in the expression double click on the object/ right click on the object to select '''edit''' from the options.
# A dialogue box on the bottom part of the screen allows us to edit the the formula structure and also enter data.
# The text or numbers in the formula structure can also be inserted by clicking on the specific place holders in the expression.
<nowiki>*</nowiki>It is important to note that once we move the cursor away from the formula the formula window closes and to insert another formula we have to follow the steps to insert formula again.
