Download or read book Hard to Solve Math Puzzles written by Derrick Niederman and published by Sterling. This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Put your mathematical thinking cap on--because even though these puzzles are toughies, they take insight and brainwork to solve, not a knowledge of calculus or linear algebra or any other kind of advanced math. Consider for a moment: * How can you divide a regular pentagon into five identical pentagonal shapes? * What is the only decade in American history to contain four prime-numbered years? * What three right triangles with integer sides have areas numerically equal to twice their perimeters? Don't worry if the answers don't spring to mind immediately; you'll have plenty of company. Compute without calculators; study the "survival of the splittest" by arithmetically analyzing a little amoeba reproduction; and investigate whether or not a rich man's children are getting a "square deal" with their inheritance. Just don't give up, because you'll have a lot of satisfaction when you figure them out.

If a border between cells contains a sign "-", a digit in a left or upper cell is one bigger than a digit in a right or lower cell. All instances of consecutive digits are shown by these signs.

Book excerpt: All puzzles are fun and entertaining. Sometimes we learn an unexpected appreciation for a particular area of learning when it is presented in an enjoyable manner. Most of us love to shop. So, Shopping Math Puzzles – word puzzles based upon shopping – will prove particularly enjoyable, even if word problems were not one of your favorite math assignments in school.Each page in this book contains twenty shopping, word-problem puzzles. Some are multiple-choice, with four possible answers provided, and some require a numerical answer. The correct answers are in reverse order at the bottom of each page.Benefits of Solving Shopping Math PuzzlesThe benefits of solving Shopping Math Puzzles are many. They help teach you how to solve problems in everyday life. You began to practice and solve mathematical word puzzles in elementary school, and you continue as an adult to encounter math word “puzzles” everyday, in real-life situations. Shopping Math Puzzles is an excellent resource to use when teachers test the understanding of a new concept. The puzzles aid in not only understanding the application of math principles, but also improve reading comprehension. Shopping Math PuzzlesProvide an Interesting and Enjoyable ActivityShopping Math Puzzles are implicitly interesting, partly because solving them does not involve a sequence of very similar steps that are designed to practice the same skill. The novelty of the puzzles adds to their interest. Solving Shopping Math Puzzles involves detective work, which most people enjoy. We become deeply involved in the process required for solving the puzzle, and relish getting the answer after having struggled.Create Greater Understanding of Mathematical ProcessesSolving Shopping Math Puzzles requires an understanding of the mathematical process. As we struggle with a puzzle, we often immerse ourselves in obtaining the solution so much that we apply mathematical methods spontaneously. This application gives us a deep understanding of problem solving methods. Promote Positive AttitudesAs we work through a shopping math puzzle, we become so involved we forget that the puzzle solving involves mathematics. Success when we find the answer helps us gain a positive attitude. This is especially effective when these Shopping Math Puzzles are used with students. Introduce and Enhance Research MethodsThe method used to solve Shopping Math Puzzles is similar to the Scientific Method used by a researcher. The solver moves step-by-step through the process. Hence, while solving the puzzle, you learn to apply the thinking processes of the scientific method.Promote Flexibility and CreativitySolving a shopping math puzzle provides an opportunity to explore ideas and to extend creativity. You need to be creative and come up with new ways of tackling problems. What works on one puzzles, may not work on the next. Flexibility in your approach is necessary.Teach General Problem Solving SkillsThe strategies and techniques used in mathematics are used to solve other types of problem. Word problems cannot be solved effectively without the four steps of problem solving:• Understanding the problem• Devising a plan• Carrying out the plan• Looking back and asking if the plan was correct and the problem solvedThese steps are applicable in any problem solving situation.Can be used to Teach Cooperative SkillsShopping Math Puzzles are ideal to work with someone else or in a group. Research has shown that talking out loud helps learning and understanding. Sharing methods of solution can help produce original ideas and increase understanding, resulting in increased enjoyment, learning, and social skills, such as communication.Allow for the Practice of Basic Math SkillsShopping Math Puzzles use basic skills in an interesting situation. Frequently, more than one mathematical function is used to derive the solution. Teachers will find these Shopping Math Puzzles a creative way to practice basic skills.

Available in PDF, EPUB and Kindle. Book excerpt: Sukrokuro combines the elements of three logic puzzles: Sudoku, Kropki Sudoku and Kakuro. It consists of a square grid with white and black cells. The goal is to fill in the white cells, one number in each, so that each column and row contains the numbers 1 through 9 exactly once. Black cells contain a diagonal slash from top left to bottom right with numbers in them, called "the clues". Such number tells the sum of numbers in consecutive cells at its right or downward. If absolute difference between two numbers in neighbouring cells equals 1, then they are separated by a dot. If a dot is absent between two white cells, the difference between the numbers in these cells is more than 1. maths puzzles - mathematical puzzles - math riddles - maths puzzles with answers - math puzzles for adults - maths puzzle games - math brain teasers - simple maths puzzles - maths puzzles with solutions - fun math puzzles - simple maths puzzles with answers - mathematical puzzles with answers - easy maths puzzles - math logic puzzles - fun math problems - math puzzles brain teasers - maths riddles with answers - mathematical riddles - math riddles for adults - math challenge
