## Main Question or Discussion Point

Hi, I am doing the Discrete math course in high school and we are doing some analynical math concepts like

vectors,

cross product,

dot product,

line equation in the form of r = a + tm,

plane equations in the form of r = a +tu +sv,

intersection of lines

and planes and planes and planes etc..

I don't really know which branch of mathematics they belong to and after reading about 3 pages of book recommendations I couldn't find anything on them. Seems of to full of calculus for the most part. Can anyone suggest some good textbooks for a beginner? My school's textbook is quite boring and horrible since it tells you how but not why. This is really hard when application questions come up on a test. You can memorize all the concepts you want but you can't solve it unless you know what it is about. This thinking "outside the box" is driving me crazy and I think I need to understand the math concepts before doing anymore homework.

My math background isn't exactly great since I focused on memorization during my early years. Thus, I forget most of the Grade 11 mathematics I learned before other than the stuff I need for my current math course. Bummer. Thanks for any recommendations.
