19. 1, 6, 7, 8, 9, 10 (476)
20. 4, 4, 5, 5, 7, 7 (900)
Goodluck and if you decide to answer please post answers with appropriate question number.
Sullivanocean, why don't you do your homework yourself, instead of cheating?
11. 846 is odd one out, should be 847
19. 1 * (6 + (((7 * 8) - 9) * 10)) = 476
20. 4 + (4 * (((5 * 5) + 7) * 7)) = 900
1 2868
2. 1717
3. 2222
4. 145
5. 238...i think theres a mistake though.. i think it should be 147, 159, 174, 186, 201, 204 etc.
6. 14
7. 330
12. 208 should be 209
13. 7359 should be 7358
14. 819 should be 7299
16. 64 should be 63
17. 4 should be 5
18. 117 should be 116
