sentence: Multiplication means that one vector is made bigger or smaller.
sentences_before: Often, for example in Euclidean space, a vector can be represented graphically with an arrow that has a tail and a head. We normally then think of addition as the tail of one vector being placed at the same point as the head of the other vector. The sum vector is the one whose tail is the tail of the first vector and whose head is the head of the second.
