Q:

If the propeller is in front, how does the plane move forward? Wouldn't it move backwards?

A:

Propellers are twisted wings that produce lift in a forward direction, we call this force thrust. The direction the thrust pushes the plane is dependent on the angle the propeller blades are at and which way they are facing, not where the propellers are located on the plane. The propellers generate a difference in air pressure between the front of the blade and the back which pushes the airplane forward.
