The perennially popular calendar that delivers a Mensa-approved challenge every day. With hundreds of brain-stumpers from logic puzzles to spatial challenges, math riddles to encoded words, each day will test your brain’s mettle: Two consecutive odd numbers have the property that when the larger number is multiplied by 11, the answer is the same as adding 43 to the product of the smaller number and 8. What are the two numbers?* If you want to check your work (or throw in the towel), answers and explanations are on the reverse side of each page.
