#### 31-Game Math Concepts: addition to thirty-one, thinking ahead. Players: best for two. Equipment: one deck of math cards. How to Play Lay out the ace to six of each suit in a row, face up and not overlapping, one suit above another. You will have one column of four aces, a column of four twos, and so on—six columns in all. The first player flips a card upside down and says its number value. Players alternate, each time turning down one card, mentally adding its value to the running total, and saying the new sum out loud. The player who exactly reaches thirty-one, or who forces the next player to go over that sum, wins the game.

#### Pierre-Simon Laplace---The marquis de Laplace was pivotal in the development of mathematical astronomy and, most significantly, statistics. He was one of the first to propose the existence of black holes; one of the central forces behind systematizing probability theory, laying the groundwork for what is now termed Bayesian statistics; one of the first to study the speed of sound.
