Functions:

function_name(arguments)

Function_name refers to what the function does.  For example, the SUM function (which finds the sum of a range of numbers that you specify) takes the form of

=SUM( )

The numbers (or references to them on your spreadsheet) go between the parentheses.

Arguments refers to the values that the function needs to compute its result.  These vary according to what function you are using.  Learning the function is largely a matter of learning how to enter the correct arguments in the function's dialog box.
