Apple II first person math rpg games

[Dripfree]

I remember playing these weird math games on the apple II in middle school. You would go around and talk to different people and they would give you stories that contained numbers. You would sort of collect the numbers from the people. Once you talked to all the people that had the numbers you needed to solve the problem you could plug those numbers into equations and solve the problems. You would then go on to another mission. There was at least couple different games that were all very similar. I remember it had some very basic wire frame graphics with white lines, and those green and purple lines you would get with the apple II. The movement created a pretty good first person 3d illusion. I remember really enjoying these games and I was wondering if anyone else remembered it so I could look them up again?
