The riddle "How does four sevens make 9?" relies on lateral thinking rather than strict mathematical operations. There are a few creative interpretations, and here is one possible explanation:

By arranging four sevens creatively:

- \( 7 + 7 - 7 / 7 = 9 \)

In this case:
1. Add two sevens: \( 7 + 7 = 14 \)
2. Subtract the result of dividing the remaining sevens: \( 7 / 7 = 1 \)
3. So, \( 14 - 1 = 13 \).

In this case
