In NMF Weekly Issue #26, Simon asks: "Is one a prime number?" James loves this question, as it lets us play with one of his favorite things: dots! (James is also the creator of Exploding Dots, a delightful math exploration for all ages.) Try this week's puzzles, featuring fun ways to determine if a number is prime, and more!
