  1. Vector quantity can’t be added, subtracted, multiplied, divided according to the ordinary algebraic rule.
  2. It can be added, subtracted, multiplied, divided according to the some special rules, like head and tail rule, Graphical method etc.

Note: Since no optimal technological solutions have been proposed so far, most distance programs still require a full-time exam session. It is impossible to say who is on the other end of the wire. In a number of cases, this is a problem and requires special measures, techniques and skills of teachers – tutors. Partly this problem is solved with the installation of video cameras on the side of the instructor and the corresponding software training. The need for a number of individual psychological conditions. As a rule, students feel a lack of practical training. There is no constant control over the trainees, which for the Russian people is a powerful incentive. The high cost of building a system of DO at the initial stage of creating a system, the costs of creating a distance learning system, the distance learning courses themselves and the purchase of technical equipment are great. High complexity of the development of courses DO. Creating 1 hour of truly interactive multimedia interaction takes more than 1000 hours of professionals.
