Entertaining word problems that let verbal types master the language of math! Math is a universal language, but it’s also the least understood and most undervalued subject taught in school. Two Trains Leave Paris: Number Problems for Word People offers an opportunity to experience math like never before. You must use the Pythagorean Theorem to figure out how far apart two ex-lovers are when they simultaneously realize that they cannot live without each other. You must use addition (and logic) to explore the ridiculous (and patriarchal!) wage gap. Throughout six math-themed chapters, readers will follow a series of characters as they apply for jobs, fall in love, get abducted by aliens, and experience many of life’s other big and small moments, all of which are dictated by—you guessed it—math! With the help of humor, mathematical history, and how-to-solve sections, Two Trains Leave Paris asks readers to help its characters find growth in the most unexpected of places: word problems. And the answers are, of course, in the back.

An ISIS terrorist planned to kill more than 500 people. He would have succeeded except for three American friends who refused to give in to fear. On August 21, 2015, Ayoub El-Khazzani boarded train #9364 in Brussels, bound for Paris. There could be no doubt about his mission: he had an AK-47, a pistol, a box cutter, and enough ammunition to obliterate every passenger on board. Slipping into the bathroom in secret, he armed his weapons. Another major ISIS attack was about to begin. Khazzani wasn't expecting Anthony Sadler, Alek Skarlatos, and Spencer Stone. Stone was a martial arts enthusiast and airman first class in the US Air Force, Skarlatos was a member of the Oregon National Guard, and all three were fearless. But their decision-to charge the gunman, then overpower him even as he turned first his gun, then his knife, on Stone-depended on a lifetime of loyalty, support, and faith. Their friendship was forged as they came of age together in California: going to church, playing paintball, teaching each other to swear, and sticking together when they got in trouble at school. Years later, that friendship would give all of them the courage to stand in the path of one of the world's deadliest terrorist organizations. The 15:17 to Paris is an amazing true story of friendship and bravery, of near tragedy averted by three young men who found the heroic unity and strength inside themselves at the moment when they, and 500 other innocent travelers, needed it most.
