📝 Explanation:
Each cell is the sum of the number in the leftmost column and the number in the topmost row. For example, in Table 1, the first cell (6 + 15) is 21, which is given as a hint.
You can check your work by adding the numbers carefully, especially when carrying over tens (e.g., 38 + 65 = 103).
This exercise helps build fluency with two-digit addition and reinforces understanding of place value and regrouping.
