MATHadazzles Junior Volume 1 Mary C Cavanagh

MATHadazzles Junior are intriguing number puzzles that sharpen solver's logical reasoning and problem solving skills, and put to use knowledge of numbers and mathematical operations. A MATHadazzles Junior puzzle is a 2-by-3 grid with circles at the ends of the rows and the columns. Each number, 5, 6, 7, 8, 9 and 10 belongs in one of the 6 grid cells. Some grid cells have clues, given as equations or inequalities, that "describe" the numbers that will fill those cells. Use the clues and your reasoning skills to place numbers, 5 - 10, so that the numbers in rows and columns add to the circle sums at the ends of those rows and columns. To make the puzzles challenging, the grid cells have a clue or are empty and 3 or 4 of the circles are empty. We tell you what numbers are missing, but you have to figure out which cell or circle to place them in so that the cell numbers "add up!" Use addition, subtraction, multiplication, and division as well as greater than and less than symbols and n as an unknown value while solving the 78 MATHadazzles Junior problems. To give you a head start, the various types of equality, inequality, and unknown symbols are described with examples at the front of the book. Answers are at the back of the book. MATHadazzles Junior are arranged in order by level of difficulty from fairly easy to more challenging. Take the book everywhere you go. It fits easily into a pocket, shoulder or handbag, and backpack. Solve MATHadazzles Junior in the morning while eating breakfast - at mid-morning for a "thinking break" - after dinner for a "brainy dessert!" Enjoy!
