konichiiwa.. im new in here...
this is the first topic that i post... actually im a college student,, im  taking up education (major in math) haha i dont know why i took the course.. anyway last monday is the start of our 2nd semester and we have this subject LINEAR ALGEBRA.. it is actually a combination of algebra and geometry! the problem there is its hard for me to find some reference book because there is only limited books of that subject in our library..

anyway...is there anybody here who can help me understand the ff.
1. dot product of a vector
2. subtraction of vector
3. spanning vector
4. translation vector
5. parametric representation
6. scalar multiplication

actually some of the explanation at the book is hard to understand..
