Calculate the resultant vectors for the following. Solve using scale when appropriate. 5a + (-2a) if a is 22 kilometres north? 5x 22 +(-2x22) = 110 - 44 ?? how do I represent them?

"In mathematics, you don't understand things. You just get used to them." -- Johann von Neumann I was talking about the direction. when you represent the vectors, +(-2a) is going to point towards south?
