Going to school we study such sciences as mathematics and logic. Sometimes the best students participate in the Olympiads where their knowledge is checked. Today in the game Rullo, we want to invite you to solve several tasks from one of the mathematical olympiads. The task will look like a puzzle game. Before you on the screen will be a game board filled with round balls with inscribed in them numbers. They will form horizontal and vertical lines broken into cells. Above them will be numbers. Your task is to activate all these numbers. For this you will have to click on the balls. In this case, the numbers you have selected should be added and give you the desired figure. Only by activating them all will you pass the level in this game.
