in R you just need to do 10-cumsum(expense). This will give you the Remaining column

More complicated than a cumsum, but for loop could look something like:
for (j in 3:5)
n[j,'Remaining'] <- n[j-1,'Remaining'] - n[j,'expense']
If your answer needs to be strictly positive, think about including a while or if statement.
