With alien spacecraft and roaring surface to air missiles, this application offers mathematical skills practice for 9-13 year olds in an entertaining game-like format.

As Math Force Delta unit commander, your job is to defend our planet from invading space aliens. The mission requires a cool head, nerves of steel, and some solid math skills! Are you up to the task?

In this fast paced challenge you are under attack from alien ships displaying randomly generated math problems. Better solve 'em quick 'cause each answer serves as the launch code for your armed and ready surface to air missile! Enter the code on time, your missile fires, and blasts those aliens out of the sky. Booyah!

Game modes for addition, subtraction, multiplication, and division are all included. Problem difficulty can also be adjusted to suit players of varying age and skill.

Scores and times are provided for each round of ten so you can track your progress. So go ahead -- play a practice round or two and blow some stuff up! Then challenge your parents and friends to a match. You'll have bombproof math skills in no time!
