I have a class that keeps a balance of "money" they earn in school.
Each week we add the total then at the end of the month they subtract thing
s they bought. So I would need a formula that adds the total for four rows
and then subtracts in the fifth row to give me a final total.

I am new to excel and am hoping I will be able to do it without too much
trouble. I am usually a pretty quick learner.
