1. First pair: 13 above, 7 in one circle. Missing number is 6 (13 - 7 = 6).
2. Second pair: 13 above, 8 in one circle. Missing number is 5 (13 - 8 = 5).
3. Third pair: 13 above, 4 in one circle. Missing number is 9 (13 - 4 = 9).
4. Fourth pair: 13 above, 9 in one circle. Missing number is 4 (13 - 9 = 4).
5. Fifth pair: 13 above, 3 in one circle. Missing number is 10 (13 - 3 = 10).
6. Sixth pair: 13 above, 6 in one circle. Missing number is 7 (13 - 6 = 7).
7. Seventh pair: 13 above, 5 in one circle. Missing number is 8 (13 - 5 = 8).
8. Eighth pair: 13 above, 10 in one circle. Missing number is 3 (13 - 10 = 3).
