The video tutorial explains the concept of addition, demonstrating that the order of adding numbers does not affect the sum. This is known as the associative property of addition, which allows numbers to be grouped in different ways without changing the result. An example with apples is used to illustrate this property, showing that regardless of how the apples are grouped, the total remains the same. The lesson concludes with a summary of the properties of addition.
