Strategy guide

- 2.Add step-by-step: 1 + 3 = 4, then 4 + 6 = 10, finally 10 + 1 = 11;
- 3.Double-check all mentioned family members to ensure none are missed in the sum.
Common mistakes
- 1.Counting only the children (3) and forgetting spouses and their children;
- 2.Missing the aunt in the total count, resulting in 10 chairs;
- 3.Overlooking that spouses and their children are separate from the original children.
