When we want to find the combination of two vectors, we take just match up the initial point of the second vector with the terminal point of the first vector, and then we draw a new third vector from the initial point of the first to the terminal point of the second. We can do this with as many vectors as we want, we just keep matching up the initial point of the next vector to the terminal point of the previous, and then draw the combination from the initial point of the very first vector to the terminal point of the very last vector.
