Cell formula
=b2/(c4+c5)
I know that in this case, c4+c5 will get performed first because it is in
brackets.

Now, here is my question.
=ROUNDUP((D6/D7),0)

In this formula, do the brackets around the division cause the division to
be performed first even though they are within the roundup brackets?
Or would it do the division first anyway, without the brackets?

I am thinking that the default procedure would do the division first without
the brackets.
But, by adding the brackets, I give the computer definite instructions which
eliminates a possible problem. (I hope this is so.)
Do you agree with my thinking?
