Arrays are arrangements of objects, pictures, or numbers in columns and rows. Repeated addition is a way to find the total number of items in an array by adding the number of items in each row or column. This helps us understand multiplication in a visual and easy way!
For example, if you have an array with 3 rows and 4 columns, you can use repeated addition ($4 + 4 + 4$) to find the total number of items, which is 12. Arrays and repeated addition make learning math fun and straightforward!
