The video tutorial explains the concept of 2-dimensional vectors, focusing on their components and how to define their sum by adding corresponding components. It visualizes vectors to illustrate their magnitude and direction, and demonstrates vector addition through graphical representation. The tutorial also explores the commutative property of vector addition, showing that the order of addition does not affect the result.
