Just underneath the diagram of the 3 S-systems at the top of this webpage;(adsbygoogle = window.adsbygoogle || []).push({});

It gives equations for Lorentz transformation between S and S'

Does x' mean the distance between the origin of frame S' and the event as measured from the origin of frame S?

And does x mean the distance from the origin of the S frame to the event as measured from the origin of the S' frame?

Thank you.
