The dot product is a simple way to add two vectors together. According to the idea of "dot product," two different vectors can be multiplied together to get a scalar number. It is a way to get something. The dot product only makes sense for pairs of vectors with the same number of dimensions. It is the product of two vectors in which one vector is projected onto the other. It tells how close two vectors are to each other. The dot is shown by a heavy dot. The angle between two vectors is smaller if the dot product is bigger. Using the dot product, we can determine how close two vectors are to each other.
