Circuits, flow of electrons?

Okay, so physics classes and Kaplan say that electrons flow from the negative to the positive terminal and that the flow of current is the opposite. But I was reading through the Nova physics book and it says that batteries maintain a constant potential difference, voltage, by chemically bringing electrons from the positive to the negative end? 😕? Why would electrons flow to the negative end? Wouldn't they be repelled by the negative charges? I am so confused, and it messed me up on one of the questions on the Kaplan FL. Help please!

Read it more carefully. It says that a POTENTIAL DIFFERENCE is created by bringing electrons to the negative end. The electrons want to flow to the positive end which is why there is a potential difference.

Also, in convention, current is typically assigned to flow in the direction opposite the actual flow of electrons. This is due to the archaic belief that "positive electrons" carried the charge.
