This math topic focuses on practicing the skill of multiplying whole numbers by breaking them down into more manageable parts. It specifically covers the multiplication of 2-digit numbers by 1-digit numbers. Each problem presents a different multiplication scenario, ranging from multiplying smaller 2-digit numbers by smaller 1-digit numbers to larger values. The objective is to decompose the 2-digit number into tens and ones to simplify the multiplication process, enhancing understanding and efficiency in solving these types of multiplication problems.
