Configuration of axles

1) Term used in goods vehicle operations to describe both the type, number and layout of axles on a vehicle/trailer (eg 4 x 2 describes a four-wheeled two-axle vehicle of which only two wheels are driven; 6 x 4 describes a six-wheel, three-axle vehicle with two driven axles - ie 4 wheels driven; 3+2 describes a three-axle tractive unit with a tandem, ie 2-axle semi-trailer, while 2+3 describes the opposite, a two axle tractive unit with a tri-axle semi-trailer).
