Subtraction Blast
The computer game Subtraction Blast at coolmath-games.com is played by using the numbers 2 and 3 on your keyboard. At the bottom of the game players see the machine that shoots the numbers 2 and 3 out of its nozzle (which is aimed by the mouse). Numbers fall from the top of the game screen toward the machine. The object of the game is to deduct these numbers to zero, thereby destroying them. Example: When the number 6 falls, players must hit the number 2 three times or the number 3 twice. If the numbers reach the machine, the machine moves closer to the top of the screen/the falling numbers. When the machine reaches the top, the game ends.
Minko's Milkshake Shoppe
In Minko's Milkshake Shoppe at fun4thebrain.com players help the friendly penguin Minko serve up yummy shakes and decorate his shop after each successful level. To make the shakes, players must click and hold the correct machine until the shake is complete. If too many orders are wrong, Minko may be forced to fire you and you'll have to start the game all over again. The customers request their shakes in the form of subtraction problems. Players then must click (and hold) the corresponding beverage glass. An example: A customer requests a "9-1." The player then must find the shake glass labeled with the answer "8," then click and hold until the glass fills and the whipped topping and cherry appear on top.

When she gets far enough ahead in the race, the game is won. In the start of the game, players can customize their Granny's wheelchair wheels, clothes and more.
