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 goto     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.  

1. A dialogue box on the bottom part of the screen allows us to edit the the formula structure and also enter data.
2. The text or numbers in the formula structure can also be inserted by clicking on the specific place holders in the expression.

*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.
