What you wrote here is syntactically wrong. When posting questions
like this, it is best to cut-and-paste from the worksheet and edit the
pasted version to simplify, if necessary.

The syntax closest to the above is:

=A1 - sum(B1,B2,...,B30) + sum(C1,C2,...,C30)

An alternative, following Jim's suggestion, might be:

=sum(A1, (C1,C2,...,C30)) - sum(B1,B2,...,B30)

But in this case, I don't think there is anything to be gained by it.
I suspect it is just confusing you.
