Basic mathematical skills are tested in this task using numerical flow charts. You will see incomplete flow charts and you simply have to complete them.
The squares have a different relationship to one another: the direction of the relationship is indicated by arrows; the mathematical operation that defines the relationship between the squares will be shown in a circle. Your job is to insert the numbers below into the empty squares so that all relationships are correct.
The solution would be …
The task is processed by using "drag and drop": move the mouse pointer over a number, hold down the left mouse button, drag the number to the desired position and release the mouse button. To remove a number from an assigned position, drag it back out of the assigned field.Furthermore, the following rule applies: All numbers must be used at least once, but can (or must) be used several times in some cases.
