Inner product

Did you ever come to the point to ask yourself what's the Inner product between a vector and a Bivectors? If you did, you may noticed soon that it doesn't have any meaningful answer yet. I got interested into this problem back when I was studying Mathematical Physics course in my bachelor degree. I wrote my finding to my professor. "wooow! You defined a higher dimensional Levi-Civita-Symbol", he saied. But my invention was much useful than that! This post is the details of that invention. If you know about vectors, and bivectors, etc. I encourage you to read to the end, because this tool is simple and super useful.
