This week’s Solve set is inspired by Hitchhiker’sSoGuide To The Galaxy by Adams (1997). The number 42 is, in The Hitchhiker’s Guide to the Galaxy by Douglas Adams, the “Answer to the Ultimate Question of Life, the Universe, and Everything”, calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years. Unfortunately, no one knows what the question is.

That being said, we have 5 Questions in our Solve set 42 that students, teachers, math enthusiasts and anyone can try!

Check out Question 1: Don’t Panic

On the faraway Planet Forg lives an advanced civilization of green sentient beings with two hands and seven fingers on each hand. Interestingly, their numbering system is in base thirteen instead of the base-ten system used on Planet Earth. “Why not fourteen?” asks Arthur, a space explorer visiting Planet Forg. “A prime base is better, so we picked the next prime down,” says Gersh, a famous Forgian mathematician. “I suppose humans should have used nine instead,” says Arthur. “I always thought something was fundamentally wrong with Earthlings,” laughs Gersh. “In your number system, what do you get when you multiply six by nine?” asks Arthur. What does Gersh answer?
