While the other answer are absolutely correct, they are very subtle in the way they appear. However one very large false-belief in electrical science is that current is taken to be "flowing" from the + terminal to the - terminal in DC current.
While it doesn't really matter which way you choose since you are dealing with close to light speed current, electrons are actually moving from - terminal to + terminal(do not get me wrong electrons are NOT moving anywhere near light speed while drifting. They are moving in the order of centimeters per second.). Hence the current actually moves from - to +.
And it would be interesting to note that not a soul in the professional area of electrical science considers the current from - to +, as it would cause inconsistency with his/her colleagues.
