9 minus zero equals 9
3 minus 5 is impossibe, hence we borrow 1 from 2 merged it with 3 to make it 13, 13 minus 5 gives 8
1 minus 6 is impossible, hence borrow 1 from 9 to make it 11, 11 minus 6 will gives 5
8 minus 2 will give 6
5 minus 7 is impossible, borrow 1 from 7 to make it 15, the 15 minus 7 gives 8
Then, lastly 7 minus 2 gives 5
Hence the answer is;
5 8 6 , 5 8 9
