Looking at what goes into a function
Most functions take inputs — called arguments or parameters — that specify
the data the function is to use. Some functions take no arguments, some take
one, and others take many — it all depends on the function. The argument
list is always enclosed in parentheses following the function name. If there’s
more than one argument, they are separated by commas. Look at a few
Takes no arguments.
Can take up to 255 arguments. Here, three cell
references are included as arguments. The
arguments are separated by commas.
In this example, the arguments are range
references instead of cell references. The arguments
are separated by commas.
=IPMT(B5, B6, B7, B8) Requires four arguments. Commas separate the
Some functions have required arguments and optional arguments. You must
provide the required ones. The optional ones are, well, optional. But you may
want to include them if their presence helps the function return the value

The IPMT function is a good example. Four arguments are required, and two
more are optional. You can read more about the IPMT function in Chapter 5.
You can read more about function arguments in Chapter 2.
