The video tutorial teaches how to multiply large numbers using two methods: the traditional algorithm and the distributive property. It begins with a basic introduction to multiplication and times tables, followed by a detailed explanation of the traditional method using paper. The tutorial then introduces the distributive property as a faster, more creative approach to multiplication. Examples, such as multiplying 425 by 12, are used to illustrate both methods. The video concludes by encouraging viewers to practice mental math and find their preferred method.
