An arrangement of objects, pictures, or numbers in columns and rows is called an array. Arrays are useful representations of multiplication concepts. This array has 4 rows and 3 columns. It can also be described as a 4 by 3 array.
Arrays are useful representations of multiplication concepts. Multiplication is similar to arrays because arrays use columns and rows to represent the digits and numbers in the equation. Addition is similar to the two because you can repeat it and you will get the same product (or sum). Equal groups are similar because it has the same number of items inside. It can be similar to all the others. So that is why they are related.
