Synopsis "MATHadazzles Volume 8: Reasoning Algebraically with Decimals (in English)"
MATHadazzles Reasoning Algebraically with Decimals are intriguing number puzzles that challenge solvers' logical reasoning and problem solving talents, and put to use their knowledge of familiar and not-so-familiar numbers, symbols, and mathematical operations. A MATHadazzle puzzle is a 3-by-3 grid with circles at the ends of the rows and the columns. Some grid cells have clues, given as equations or inequalities, that "describe" the values of n that will fill those cells. The solver's job is to use clues to place the decimal numbers, -2.0, -1.5, -1.0, -0.5, +0.5, +1.0, +1.5, +2.0, and +2.5 in the nine cells of the grid so that the numbers add up to the given sums. While solving MATHadazzles you will learn about various types of numbers and computations with them. All 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. Contributors to the book were high school students who participated in the NSF-funded App Maker Pro project (#1509105) at Arizona State University. They wrote, edited, and rewrote MATHadzzles for you to enjoy. Take the book everywhere you go. It fits easily into a pocket, a backpack, and a shoulder or hand bag. Solve MATHadazzles in the morning while eating breakfast - at mid-morning for a "thinking break" - after dinner for a "brainy dessert!" Enjoy!
