👉 Squad math is a method used to calculate the total number of unique players in a team when considering overlaps, such as players who play multiple positions or are part of the same squad. It involves a formula that accounts for the basic principle of inclusion-exclusion to avoid double-counting these players. The formula is: \( |A \cup B| = |A| + |B| - |A \cap B| \), where \( |A| \) and \( |B| \) are the numbers of players in two distinct squads (or positions), and \( |A \cap B| \) is the number of players in both squads. For multiple squads, you extend this to \( |A_1 \cup A_2 \cup... \cup An| = \sum |A_i| - \sum |A_i \cap A_j| + \sum |A_i \cap A_j \cap A_k| -... \), where you add and subtract the intersections of three, four, etc., squads to ensure each player is counted exactly once. This method is crucial in sports analytics and team management for accurate squad composition analysis.
