Vectors

This week in advanced math we have just finished chapter 12. Chapter 12 was about vectors. We took a test on vectors and I thought that the test was fairly easy. The hardest part was the 4x4 matrix which wasnt really that hard; just time consuming. Today I am going to teach you how to add and subtract a vector. This is probably one of the easiest things you will learn to do.

DIRECTIONS:
1. You should make sure you have a vector, u and v are always vectors.
2. Then you should add x1 to x2 and you will come out with a new vector.
3. You should do the same thing for subtraction just simply subtract the vectors.

EXAMPLES:
u=<4,5> v=<3,4>

Addition:
Find u+v
<4,5>+<3,4>
answer:<7,9>

Subtraction:
Find u-v
<4,5>-<3,4>
answer:<1,1>

*This is the easiest thing you will learn to do with vectors from my point of view.
*Just remember add the x's and add the y's and the same rules apply for subtraction.
