The dot product is a way to combine two vectors to get a single number. You multiply the matching components of the two vectors and then add those results together. For example, if you have two 2D vectors, you multiply the x-values together and the y-values together, then add those two numbers. The result tells you something about how much the two vectors point in the same direction. If the result is zero, the vectors are at a right angle to each other. There’s also a geometric way to understand
