Subtraction with the tank is the online maths game to practise some subtraction by moving the tank towards the safe mines on the ground. Use the mouse to play this game, clicking on the side you want to move the tank to. You can also stop the tank so you can do the subtraction calculation and think about your answer. To do this, click on the tank. Tap the tank again to start it up again, when you know your answer. If the tank passes the correct mine, it will not explode. If you make a mistake and don't subtract correctly, the tank will be destroyed by the soil bomb.
