I have a multiple-step simple formula that I need to implement, I have attached a sample below, essentially I want to add A1+B1 then divde it by C1, I then want that result to sum with all the other results below it (ex. A2+B2/C2 etc.). The part I dont know is how to do that for mutiple rows without throwing in an additional column. Basically I need to do whats in the gray boxes in 1 formula without needing those two gray columns to pull from, my explanation is confusing but the problem is simple I know it. PLease help! thanks everyone :-]Example Multi Step Math.xlsx
