Explanation:
We need to convert each expanded form (like 700 + 10 + 4) into a single number, then match that number to the list at the top. Each number corresponds to a letter (like 714 → T). Then we write the letter in the blank.

Let’s do each one:

1. 700 + 10 + 4 = 714 → T (already done)
2. 100 + 80 + 1 = 181 → Look at the top row: 181 appears — and it's under the second box of the second group. The letter there is I.
3. 20 + 8 = 28 → Top row: 28 is the third box in first group → E
4. 400 + 20 + 9 = 429 → Top row: 429 is in the second row, second box → A
5. 900 + 90 + 2 = 992 → Top row: 992 is first box in last group → F
6. 100 + 60 + 4 = 164 → Top row: 164 is second box in first group → H
7. 500 + 30 + 6 = 536 → Top row: 536 appears twice — in third row (3rd and 4th boxes) and also in second row (last box). But the clue says “there may be more than one”, and we just need a matching letter. Looking at the third row: 536 is 3rd and 4th boxes — both are blank, but the letter shown for 536 in the puzzle layout is N (in the third row, 3rd box). So N.
8. 100 + 1 = 101 → Top row: 101 is last box in last group → Y
9. 200 + 50 + 3 = 253 → Top row: 253 is 5th box in third row → O
10. 600 + 50 + 3 = 653 → Top row: 653 is first box in third row → C
11. 200 + 30 + 9 = 239 → Top row: 239 is first box in second group → V
12. 300 + 40 + 6 = 346 → Top row: 346 appears twice — 3rd and 4th boxes in second group. The letter shown for 346 in the puzzle is L (in the last group, second box — wait, no: look again — in the second row, 346 is 3rd and 4th; in the last row, 346 is second box, and that box has no letter yet, but the clue shows letters only where marked. However, in the grid of numbers at top, the last group has: 992, 346, 101 — and the middle one (346) aligns with letter L (from the superhero clues below — the owl character is labeled L, and it's placed under the column with 346 in last group). So L.

So the letters are:
T, I, E, A, F, H, N, Y, O, C, V, L
