In this test, a network of numbers connected with vertical and horizontal arrows is shown, where one or more elements are missing. Each arrow depending on its four possible types of orientation-direction (vertical upward, vertical downward, horizontal left-to-right and horizontal right-to-left) performs an operation that you need to find out. Then you can calculate the missing number indicated with question mark.
An example is shown in the following picture.
