The arguments inside the parentheses of a function provide what purpose? arguments define the function category
arguments indicate to Excel that you are starting a formula
if the arguments are incorrect the function will still work as
expected
arguments are the data that the function requires to work

Arguments are the data which u give to your function when any of the function is to be called.

Explanation:

parentheses serve multiple purposes, depending on the language’s syntax. Since most popular languages these days derive their syntax from C (the group of “curly brackets languages”), I’ll answer in that context.

Apart from simple syntactic usages, like in function declarations, definitions, and calls, their biggest use is to enforce a specific order of evaluation in expressions.

There is an intrinsic order of evaluation (precedence of operators) within each of those languages, but they can be very, very tricky. Also, some constellations of expressions are not even defined by the language, thereby leading to undefined behaviour, which is the programming equivalent to entering hell.

i can't answer your question in very sad situation.

but if your situation is very bad, then you can find happiness by thinking about your past that has full of happiness.

or you should do meditation for some time to get rid off from that bad situation.
