Explanation:
We need to find the number described in each clue by combining the ones and tens.

Remember:
- “Ones” are the single digits (0–9) — they go in the ones place (rightmost digit).
- “Tens” mean groups of 10 — so 6 tens = 6 × 10 = 60.
- To get the full number, add: (tens value) + (ones value).

Let’s solve each one step by step:

1. I have 14 ones and 6 tens.
→ 14 ones = 14
→ 6 tens = 6 × 10 = 60
→ Total = 14 + 60 = 74

2. I have 4 ones and 8 tens.
→ 4 ones = 4
→ 8 tens = 80
→ Total = 4 + 80 = 84

3. I have 5 ones and 5 tens.
→ 5 + 50 = 55

4. I have 1 one and 8 tens.
→ 1 + 80 = 81

5. I have 3 ones and 8 tens.
→ 3 + 80 = 83

6. I have 6 ones and 7 tens.
→ 6 + 70 = 76

7. I have 7 ones and 6 tens.
→ 7 + 60 = 67

8. I have 5 ones and 7 tens.
→ 5 + 70 = 75

9. I have 4 ones and 5 tens.
→ 4 + 50 = 54

10. I have 13 ones and 6 tens.
→ 13 ones = 13
→ 6 tens = 60
→ Total = 13 + 60 = 73

Let me double-check each:
1. 60 + 14 = 74
2. 80 + 4 = 84
3. 50 + 5 = 55
4. 80 + 1 = 81
5. 80 + 3 = 83
6. 70 + 6 = 76
7. 60 + 7 = 67
8. 70 + 5 = 75
9. 50 + 4 = 54
10. 60 + 13 = 73

All correct.

Final Answer:
74, 84, 55, 81, 83, 76, 67, 75, 54, 73
