A Magic Square is a grid of numbers arranged in such a way that the sum of each row, column, and diagonal is the same. This constant sum is known as the "magic constant." Magic squares can vary in size, with the smallest being a 1x1 square, which contains just one number. The most famous example is the 3x3 magic square, which uses the numbers 1 to 9. Magic squares have been studied for centuries and appear in various cultures, including ancient China and India. They are often associated with mathematics, puzzles, and even art, as they can create visually appealing patterns.
