*solved it please remove

Can someone please tell me how to find the cross product between two seven dimensional vectors?

For instance, if the first vector is <a,b,c,d,e,f,g> and the second vector is <h,i,j,k,l,m,n>, what would the new vector, that we'll call <o,p,q,r,s,t,u>, 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 ( ... 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...

Let's leave the above, as others may be interested. The rows are used to form products that are added, as is usual for matrix multiplication.
