When Franklin discovered electricity he randomly decided which charge he named positive and which negative. Unfortunately he named them so that the later discovered electrons are now negative. This makes several things in physics unnecesserarily complicated. Like that when you add electrons to an atom it becomes negative and when you remove them it becomes positive. Also now the current goes from plus to minus, but the actual electron flow goes from minus to plus, making life harder electrical engineers.
Uhm, it's a bit of science nerd humor I'm afraid, but I got so confused with all the current goes here, electrons the other way thing in physical chemistry that I can horribly relate to it. :)
