An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplication concepts (among other ideas in mathematics). This array has 4 rows and 3 columns.Notice that the rows in each array are equal in length. Think of the rows as equal groups.
