None of the equations are correct.
──────────────────────────────────────
Explanation:
Let’s check each puzzle one by one:
- Puzzle 81: 8 + 6 = 5 → 8 + 6 is actually 14, not 5.
✘
- Puzzle 82: 8 + 5 = 2 → 8 + 5 is 13, not 2.
✘
- Puzzle 83: 10 + 5 = 4 → 10 + 5 is 15, not 4.
✘
- Puzzle 84: 25 + 6 = 23 → 25 + 6 is 31, not 23.
✘
- Puzzle 85: 35 + 6 = 25 → 35 + 6 is 41, not 25.
✘
- Puzzle 86: 10 + 0 = 2 → 10 + 0 is 10, not 2.
✘
- Puzzle 87: 14 − 7 = 15 → 14 − 7 is 7, not 15.
✘
- Puzzle 88: 30 − 7 = 31 → 30 − 7 is 23, not 31.
✘
- Puzzle 89: 66 + 5 = 57 → 66 + 5 is 71, not 57.
✘
- Puzzle 90: 23 + 15 = 0 → 23 + 15 is 38, not 0.
✘
All ten equations are wrong — none match real arithmetic. So the correct answer is:
none are correct.
