Vector addition is just a matrix addition. When adding vectors, we connect the initial point of the second vector to the terminal point of the first vector. And when subtracting vectors, we have to be careful with the order of the vectors.
To add vectors, connect the terminal point. When subtracting vectors, take the exact same vector and move it the opposite directions.
The dot product is a way of multiplying two vectors together. It just takes the first component of each vector, and multiplies them together, and then adds the product of the second components.
