I'm studying for my PE (licensing) exam, and I need help with this problem. I don't need help solving it (at least not yet), just with the way it's drawn. I've never seen a circuit with arrows coming out of the nodes like this. I'm guessing that they're supposed to be currents entering or exiting the nodes, but I was hoping someone here would know for sure. I'm supposed to be solving for the current across R5, if that helps any.
Thanks for any help!
