I'VE GOT YOUR NUMBER! Once upon a time--far into the future--the brilliant Professor Nimbledome will make basic arithmetic more fun than bubble gum. He will write the problems on his electronic blackboard--and then put possible answers into orbit. The students will have to run an exciting electronic race for the correct answer to score their points. Professor Nimbledome's electronic blackboard will be so sophisticated that it will even identify the math proficiency of the players. It will offer its challenges at that level--and slightly above. By special arrangement with the United Planets Time Travel Commission--you can play with this bit of tomorrow--today.
