Leave the skill as “Addition,” leave the first operand as 1, change the second operand to 9, and leave the level at “Beginner.” Then you may enter your name at the bottom and click “Start.” Press any key to start the game, then read the addition problem as it comes down the screen. Use the arrow keys or “ASDFG” keys to move from side to side to select the correct answer. Leave your answer highlighted until the addition problem reaches the bottom of the screen. If your answer is correct, a point will appear in the green circle. If your answer is incorrect, or if you do not choose an answer before the problem reaches the bottom, a point will appear in the red circle.
