Christmas Tree Addition (Christmas Tree Addition)
Start preparing for Christmas in Christmas Tree Addition. You need to decorate ten fir trees and do it with the help of dexterity and mathematics. The snowman will toss the balls so that they collide in the air. Your task is to get the ball with the desired value and place it on the Christmas tree, which is on the right. Watch out for ball collisions. If they are the same in form and value, then as a result the numbers are summed up. Balls of different colors will minus their values in the Christmas Tree Addition when colliding.
