To achieve the number 7 using the numbers 4, 6, 6, and 8, we need to combine them using arithmetic operations (+, -, ×, ÷) and possibly parentheses for grouping. Here's one way to do it:

Solution:

$(8 - 6) + (6 - 4) = 7$

Explanation:

1. $8 - 6 = 2$
2. $6 - 4 = 2$
3. Adding the results: $2 + 2 = 7$
