For instance, if the first vector is and the second vector is , what would the new vector, that we'll call , be if it's the cross product of the first two? I'm not a math major and can't really understand advanced math terms or explanations. I literally need someone to tell me that o =, p =, q =, etc. I've been looking at the wikipedia page (http://en.wikipedia.org/wiki/Seven-dime ... ss_product)for a while, but it's just too esoteric for me to understand. Ugh never mind, figured it out. For anyone who cares, if you go to the wiki link, it's under coordinate expressions - the part where it says X x Y = (x2y4 - x4y2 ....... Each row is the new value of the new vector. I have absolutely no idea why they are adding each row together. Why is it I struggle with these things until five minutes after asking other people...
