Electrons move from negative to positive but all the conentions of circuit analysis use a positive to negative flow. The answer comes out the same no matter which convention you use.

Electricity does not move , what moves is the electrical charges with in the conductor. So the electrons having a negative charge move towards the positive terminal.
This is called electron current.
Conventional current however is assumed to move from the positive o the negative terminal.

Current is thought of as flowing from the positive to negative terminals in all electrical applications. However, the electrons are really flowing from the negative to positive terminals. Keeping in mind that electrons are NEGATIVE, you can think of this as the negative charge moving from the negative to positive terminals, thus, making the negative terminal less negative as time goes on.
One way to think of it is through the concept of "holes." When electrons move throughout a material, they are jumping from one vacant spot to another in the valence band of atoms (which is why the number of vacancies in the valence band give elements their conductive properties). So, while electrons are known to be negative charges that are moving in a general direction (- to +), the vacancies that they leave behind can be thought of as "holes" with positive charge (please note - these do not exist, they are merely a concept to help conceptualize the flow of charge). The positive charge holes move in the direction opposite of the electrons, and so positive charge moves from the + to - terminals (only as a result of the real, physical negative charge moving in the opposite direction).
Hope that helps to clear it up. It can be confusing.

The word "Electricity" incorporates lots of concepts, but in another way it can be defined as the flow of current within a circuit.Within current there are positive and negative charges, this charges have the freedom to move randomly, their direction of motion in a circuit can vary within intervals,thus they have an alternating property as well, but the scientific conventional direction is from positive to negative. Note that there is AC (alternating current) & DC (direct current)

Electrons are negative particles. For an electron to move it has to go where there are less electrons. So where the electron comes from is more positive than where the electron is moving to.
So the flow is from negative to to even more negative.
So positive to negative is ok.
Hope this makes sense.

it flows from negative to positive since it is carried by electrons.
In case of electric flow in liquids like salty water it flows in both way by positive and negative ions.

electrons travel from negative to positive but electricity is said to move from positive to negative.
this is a paradox
