+- Vectors
+	- have both magnitude and direction
+	- Operations on vectors
+		- scalar multiplication
+			- multiply both components of vector by the same scalar
+			- doensn't change the direction of the vector
+		- addition
+			- add the corresponding components together
+			- same as putting initial point of one on terminal point of other
+		- subtraction
+			- v - w can be represented as v + (-w)
+			- when initial points are the same, difference is the vector formed between the two terminal points
+			- can also add the negative of one vector to the other
+		- Component form
+			- when a vectors initial point is at (0,0) it can be written in component form
+			- <x, y>
+		- Magnitude
+			- Pythagoras
