Author Description

MATHadazzles are intriguing number puzzles that sharpen your logical reasoning and problem solving talents, and put to use your knowledge of familiar and not-so-familiar numbers and mathematical operations. Your job is to use clues to place numbers -5, -4, -3, -2, -1, 1, 2, 3, 4 in a grid so that the numbers in rows and columns add to the circle sums at the ends of those rows and columns. No doubt you recall odd and even numbers, but do you know about square numbers and square roots and, oh yes, exponents? What about prime and composite numbers? Factors and multiples? The Fundamental Order of Operations? Learn about these and other types of numbers and computations with them while solving the 78 MATHadazzle problems. To give you a head start, the various types of numbers and computations are defined at the front of the book. Answers are at the back of the book. MATHadazzles are arranged in order by level of difficulty from fairly easy to super challenging. Take the book everywhere you go. It fits easily into a pocket, shoulder or hand bag, and backpack. Solve MATHadazzles in the morning while eating breakfast – at mid-morning for a “thinking break” – after dinner for a “brainy dessert"! Enjoy!
