Vector Sum

It is an exercise for the development of intuitive, visual understanding of vectors and their properties, and, at the same time, for the development of eye estimation. Add up together the six vectors shown on the diagram. Find the order number of the spot pointed by the sum vector? The beginning point (tail) of the sum vector is located at the 0 spot. Beginning points (tails) of the initial vectors are located at 0 spot too.
Задача на развитие интуитивного, образного понимания векторов и их свойств и, одновременно, на развитие глазомера. Сложите шесть изоброженных радиус-векторов. Найдите номер пятна, который достигает голова вектора-суммы. Начало вектора суммы, как и исходных векторов, расположено на пятне с номером 0?
