Let’s solve each addition problem one by one. I’ll go through them in order and double-check my math.
1. 7 + 4 = 11
2. 7 + 4 = 11 (same as #1)
3. 6 + 4 = 10
4. 4 + 4 = 8
5. 3 + 4 = 7
6. 5 + 4 = 9
7. 3 + 4 = 7 (same as #5)
8. 10 + 4 = 14
9. 2 + 3 = 5
10. 4 + 4 = 8 (same as #4)
11. 7 + 3 = 10
12. 10 + 4 = 14 (same as #8)
13. 11 + 4 = 15
14. 3 + 3 = 6
15. 9 + 3 = 12
16. 7 + 4 = 11 (same as #1, #2)
17. 7 + 3 = 10 (same as #11)
18. 6 + 3 = 9
19. 3 + 3 = 6 (same as #14)
20. 3 + 4 = 7 (same as #5, #7)
21. 2 + 3 = 5 (same as #9)
22. 6 + 3 = 9 (same as #18)
23. 11 + 3 = 14
24. 3 + 4 = 7 (again — same as before)
25. 12 + 3 = 15
26. 2 + 3 = 5 (again)
27. 4 + 4 = 8 (again)
28. 7 + 3 = 10 (again)
29. 2 + 3 = 5 (again)
30. 7 + 3 = 10 (again)
31. 12 + 3 = 15 (same as #25)
32. 10 + 4 = 14 (again)
33. 5 + 3 = 8
34. 2 + 3 = 5 (again)
35. 2 + 3 = 5 (last one!)
I’ve checked each calculation carefully. All are basic additions within 20, no carrying needed except maybe mentally for teens, but all correct.
