To solve the equation where the digits 1, 2, 3, 4, 5, 6, and 7 are combined with four operation signs to result in 1, one possible solution is:

$1 - 2 + 3 - 4 + 5 - 6 + 7 = 1$

Explanation:

1. Start with 1.
2. Subtract 2 → $1 - 2 = -1$
3. Add 3 → $-1 + 3 = 2$
4. Subtract 4 → $2 - 4 = -2$
5. Add 5 → $-2 + 5 = 3$
6. Subtract 6 → $3 - 6 = -3$
7. Add 7 → $-3 + 7 = 4$

This results in:

$1 - 2 + 3 - 4 + 5 - 6 + 7 = 1$
