hi SuperLynx
Vectors are used in many ways. I was trying to show a movement vector of 6 across and 2 up. That's why I put an arrow on the red line. Sometimes vectors are written as a row rather than a column. I prefer the column format because you don't have any confusion with coordinates.
Have a look at

Isn't that vector 2,7 ?

hi SuperLynx
No dummy. Everyone has to start somewhere. But how basic do you want? (see diagram)

This is going to sound like a dummy, which I am since I have forgotten some of this stuff. Do you know any real basics teachings so I can build from that ?

hi SuperLynx
The MathsIsFun teaching pages cover the dot product. I would recommend this:
http://www.mathsisfun.com/algebra/vecto … oduct.html
And at the bottom there are some "test yourself" questions.
Why not start there ?
Also, if you search my posts you'll find I've helped people in the past on vector topics.
Post here if there's still a difficulty.

Hi. I'm looking for some help in understanding Trigonometry and Algebra. Specifically, vectors, matrices & scalars. I hope someone can help me, I have searched on the subject, although nothing I could understand. How do you multiple vectors, what is a dot product, I suppose best to start with that, I've already begun learning, but any resource or your own personal explanation would be helpful.
