I've always used subtractions in SUM like =sum(c1-c2). It always works, but I tried =sum(c1-c2-c3) results in an error.
Also, i am not very sophisticated in learning Excell but always use just simple formulae. However, I tried also use my logic to create a formula, but it's not working? The formula I tried is:
=sum((c1-c2)-(e1:e10)) e1 to e10 consists of itemized numbers that are added up for the cell c3.
Please help. Thanks
