    I’m not getting left handed vs right handed. Right handed means negative values go right? Why would anyone do that?

      Right handed means that when you curl the fingers on your right hand from +X towards +Y, your thumb points towards +Z.

      Someone else was explaining how to tell left from right handed. Buy why is it important? If you do math and physics, you almost certainly would use a right hand system. That means all formulas are derived with that in mind. If you try to use them in the left handed system, you are going to have a horrible time trying to figure out which of all terms need to have their sign flipped.
