**To solve this problem, we use complementary counting: first calculate the total number of arrangements, then subtract the number of arrangements where the two artifacts are adjacent.** A growing number of users are exploring innovative solutions to complex challenges, and this approach offers a fresh lens for understanding seemingly tangled systems. This method starts with envisioning all possible configurations, then systematically removing those that fall into a restrictive pattern—specifically, when two key components appear side by side. Applied beyond abstract math, complementary counting reveals hidden clarity in decision-making, trends, and digital ecosystems across the U.S. --- **Why Complementary Counting Is Gaining Attention in the U.S. Context**
