Entering a Function
A function is a predefined formula that performs calculations by
using specific values in a particular order. The values are called
arguments. The arguments can be numbers, lists, cell names,
cell ranges, etc., depending on what the function requires. The
arguments are enclosed in parentheses, and a comma
separates each argument.
=sum(A3:A25)
Note
The ending parenthesis is required!
•
When a function uses a cell name or range as arguments, it
must be preceded by an equal sign; otherwise, no equal sign
is necessary.
•
When the function is not preceded by an equal sign, only the
resulting value of the function is saved in the cell; the entire
function and its arguments are not saved.
