Multiplication Concepts and Area Model

The video tutorial explains how to multiply two-digit numbers using a rectangular model. The problem 18 times 24 is set up by breaking numbers into expanded form and drawing a rectangle. Each section of the rectangle represents a multiplication problem, which is solved step-by-step. The individual products are then combined to find the final result of 432.
