## The Concept of a Function

Spreadsheets generally have a large number of
integrated functions for processing data. There are hundreds,
categorised as follows:

- Arithmetic functions that offer basic tools to process numerical data
- Statistical functions that have analysis tools, averaging tools
- Date functions that process and convert dates
- Logic functions that process logic data (AND, OR, etc.)
- Financial functions that process monetary data

## Function Syntax

A function is characterised by its name (written in uppercase by convention), followed by parenthesis. It contains *arguments*
(inside the parenthesis), which are a set of values, seperated by
semi-colons, to which the function applies. Thus, a function called *FUNCTION* would be written as follows:

FUNCTION(argument1; argument2; etc.)
