Mastering 3-Digit Multiplication with the Standard Algorithm

Instructor Boots guides students through multiplying three-digit numbers using the standard algorithm. The video covers the steps involved, including lining up digits, multiplying from right to left, and understanding place value. Three example problems are solved: 365 x 276, 848 x 264, and 742 x 514. The video emphasizes understanding the 'why' behind each step and offers additional resources for further practice.
