Ok, I often hear that things become more easily understood in higher dimensions. I also hear that it is easier to express them in math than with words. But what does equations that express higher dimensions look like? Is it something as simple as (x,y,z,w)? I might be over thinking this far more than I should, but what are some examples of equations that take advantage of higher dimensions? For example something like x2+y2+z2=w2. Is something like that a example?
