__Number Properties__


 * **Property** || **Addition** || **Multiplication** ||
 * Communicative || a+b = b+a || axb = bxa ||
 * Association || (a+b)+c = a+(b+c) || (ab)(c) = (a)(bc) ||
 * Distributive || a(b+c) = ab + ac || a(b+c) = ab+ac ||

Scalar – has magnitude only (height, mass, speed,age) Vector – has magnitude and direction (displacement, velocity, force)

__Representing Vectors__ 1. Words- 5km at an angle of 20° to the horizontal 2. Diagrams – on attached doc Example- on attached doc

Magnitude of Vector written using absolute value brackets

__Direction__ 1. true bearing 2. compass bearing

__Types of Vectors__

1. Parallel vectors - Same __or__ opposite direction

2. Equivalent Vectors - Same magnitude and direction - They can have different locations

3. Opposite Vectors - Same magnitude but opposite direction

For teamwork Tuesday we worked on Add and subtract Vectors handout

Resultant – the result of adding / subtraction vectors together

Read TIP TO TAIL

The resultant vector start at the first tail and ends at the last tip

__**Applications for Vector Addition**__

__**Overview:**__ Today in class we did a Mid-Unit Vector Review, where we let vector AX = a and vector AY = b in the rectangle ABCD. It was good practice for representing vector segments with variables and expressing their resultant vectors in addition statements of these variables.

**__In-Class Worksheet__:** **Mid Unit Vector Review** Answers were taken up in class.
