You and Alexa are on Mars mining gems from the Red planet. You will be asked a series of increasingly difficult addition and subtraction questions to drill deeper into the planet. As you dig deeper, you will find rare gems. Occasionally you will get stuck and need to answer a challenge question to break through the hard crust. Collect gems and try to reach greater depths each day!
