Numerical tables and their properties

A numerical table is a rectangular array of numbers arranged in rows and columns. Each entry in the table can represent a value, such as a score, measurement, or result. Tables can be used to organize data, find patterns, and solve word problems, especially in contexts like tournaments or schedules.

Important properties

• Each cell is identified by its row and column.

• Rows and columns can represent different categories (e.g., teams, rounds, players).

• Tables can be symmetric (if the value in row $i$, column $j$ is the same as in row $j$, column $i$) or asymmetric.

• Row and column sums can provide useful information (e.g., total points scored by a team).

• Tables can be used to systematically count possibilities or outcomes.
