Column 1: 7 - 9 is < 0, we need to borrow 10. Column 1: 10 + 7 - 9 = 8

Column 2: 8 - 8 is <= 0, and we needed to borrow on the last column. Therefore, we need to subtract 1 for the borrow in the previous column, and then add 10 for another borrow for this column. Total borrowing is 10 - 1 = 9. Column 2: 9 + 8 - 8 = 9

Column 3: Since we borrowed on the last column, we take it out of 9 Column 3: 9 - 1 - 0 = 8
