DynaPlus for iPad app for iPhone and iPad

DynaPlus provides a fun way for you to practice the addition of signed numbers while navigating your space ship to shoot down space aliens attacking from the planet Arithme.

Your ships sensors detect the approaching enemy ships and you must correct your course to match theirs. Be sure to shoot the enemy ship before it enters the Red Zone -- or it will blow up your ship.

There are five levels of play. In Level 1, your sensors detect enemy ships that are within + or - 5 units of your position. As you progress, your sensors improve and can detect enemies that are further away.

OPTIONS
Use the Options Menu to adjust the game speed to match your ability.

ENDING THE GAME

To end the game without waiting for all of your ships to be blown up, tap the Pause button and choose End the Game.
