The dot product is a means for taking two vectors, which have magnitude and direction, and multiplying them to get a number, or a scalar. The topic is typically taught in College Level Calculus classes, in topics such as Vector Calculus and Multivariate Calculus.

To multiply two vectors, you’ll need to actually break them down to their x, y, and z components first so that you can multiply their respective components and get your solution.

In the example that Chegg Vector Calculus tutor, Scotty G., gives us, we see that two vectors, v and u, have 3-dimensional components namely x, y, and z. When their components are multiplied and the x, y, and z multiples are summed, you get your scalar solution.
