Description: Sterling Publishing Company, Incorporated, 2005. Paperback. Pp: 128. Take an appealingly illustrated fun test of your perceptual ability, math smarts, and knowledge combinations and probabilities. See how fast your eyes can discern the one sulking face nearly hidden in a large group of smiling "Spikeheads." Figure out how many different shapes went into creating two tessellation patterns. It takes mental gymnastics to rearrange a human tower of 36 red and blue acrobats so that they fulfill a set of rules about where they stand and who they stand next to. Calculate how many different ways the eight Knights of the Round Table can be seated without anyone having the same two neighbors more than once. There's also fascinating background on the theoretical principles that underlie the solutions. ISBN: 9781402723445. Cond./Kwaliteit: Goed.
