๐Ÿ“š Quick Study Guide

    ๐Ÿ”ข Definition: A multiplication array is a rectangular arrangement of objects (like dots or items) into rows and columns. โž• Rows and Columns: Rows run horizontally, while columns run vertically. โž— Multiplication: The total number of objects in the array is found by multiplying the number of rows by the number of columns. So, an array with 3 rows and 4 columns represents $3 \times 4 = 12$. ๐Ÿ“ Visual Representation: Arrays provide a visual way to understand multiplication and can help with solving multiplication problems. ๐Ÿ’ก Commutative Property: Remember that the order doesn't matter! $a \times b = b \times a$. A 2x5 array has the same number of items as a 5x2 array.
