MathPup Defense Basic

The Snow Noids are trying to take over MathPup's fort.  Help MathPup fight them off by using the snow cannons and your math (addition, subtraction, multiplication, division) skills.  Don't let them get past MathPup and watch out as on later levels they start bringing shields!

Click on a cannon in front of a Snow Noid to move MathPup over to it.  Then click the number at the bottom of the screen to fire that number snowball at the Noid.  If the number answers the Noid's problem then it will be knocked off the screen.
