Since the user has set all options (ExplainAnswer, TeachTopic, GeneratePractice) to false, I will not include those sections. However, per instruction, I must still work through each problem step by step and verify calculations before providing the final answers — even if no explanation is requested.
Let’s solve each addition problem one by one. All are 2-digit additions without regrouping, meaning we add tens with tens and ones with ones separately.

Row 1:
1.
14 + 20
Tens: 10 + 20 = 30
Ones: 4 + 0 = 4
Total: 30 + 4 =

23 + 10
Tens: 20 + 10 = 30
Ones: 3 + 0 = 3
Total: 30 + 3 =
33

99
15.
70 + 27
Tens: 70 + 20 = 90
Ones: 0 + 7 = 7
Total: 90 + 7 =
97
16.
60 + 38
Tens: 60 + 30 = 90
Ones: 0 + 8 = 8
Total: 90 + 8 =
98

Row 5:
17.
36 + 43
Tens: 30 + 40 = 70

20.
29 + 30
Tens: 20 + 30 = 50
Ones: 9 + 0 = 9
Total: 50 + 9 =
59

All problems solved and verified. No regrouping was needed in any case — as expected from the worksheet title.
Final Answer:
34, 33, 47, 26, 94, 35, 66, 98, 63, 85, 97, 99, 94, 99, 97, 98, 79, 89, 99, 59
