I am trying to fiuger out how to write this formula. I want Cell I3 to add the amout i put in say D6, then i want a different cell say D7 to subtrace the amout I put in it it from I3, and a different say D8 cell to replace I3 with the amount I put in it. The main problem I am having is getting the next equation to perform from the answer of the last equation. I want all these different cell to perform different equation with the anwer of I3.
