  difficult math riddles with answers: Math with Bad Drawings Ben Orlin, 2018-09-18 A hilarious reeducation in mathematics-full of joy, jokes, and stick figures-that sheds light on the countless practical and wonderful ways that math structures and shapes our world. In Math With Bad Drawings, Ben Orlin reveals to us what math actually is; its myriad uses, its strange symbols, and the wild leaps of logic and faith that define the usually impenetrable work of the mathematician. Truth and knowledge come in multiple forms: colorful drawings, encouraging jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone. Orlin shows us how to think like a mathematician by teaching us a brand-new game of tic-tac-toe, how to understand an economic crises by rolling a pair of dice, and the mathematical headache that ensues when attempting to build a spherical Death Star. Every discussion in the book is illustrated with Orlin's trademark bad drawings, which convey his message and insights with perfect pitch and clarity. With 24 chapters covering topics from the electoral college to human genetics to the reasons not to trust statistics, Math with Bad Drawings is a life-changing book for the math-estranged and math-enamored alike.
  difficult math riddles with answers: Entertaining Mathematical Puzzles Martin Gardner, 1986-10 Playing with mathematical riddles can be an intriguing and fun-filled pastime — as popular science writer Martin Gardner proves in this entertaining collection. Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem. Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the youngest and rowdiest branches of modern geometry, offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed. Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked. Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader want to study the subject in earnest and explains some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle. 65 black-and-white illustrations.

LAST DAYS! ★ Are your little customers looking for difficult math riddles and brain teasers? Math riddles that make math exciting and engaging can teach kids the value of learning. They mix up the tired formula of worksheets while showing kids how they can apply math to their daily lives in unique ways. Letting kids figure out the answers to these puzzles teaches them problem-solving skills that they can apply to all areas of life. It also allows them to feel the joy that comes with working hard on something and coming up with the correct solution. Providing gentle guidance towards the correct answer when your child is uncertain shows them that you are willing to take an active role in encouraging and supporting their education. Math riddles teach critical skills while encouraging cooperation and engagement from the whole family. These riddles typically encourage the application of pattern recognition, logical thinking, and problem-solving in order to reach the answers. Sometimes they may require a series of calculations to derive the right answer. They cover a wide range of different topics and lessons depending on the age group the riddles are made for and the difficulty level of the riddles. Some math riddles only require addition with single numbers to solve, while others may involve the use of calculus principles. Since this book contains riddles geared towards children between the ages of 8-11, the range of math topics has been simplified to only include the relevant lessons. The primary math concepts the riddles in this book deal with are arithmetic, times tables, factors, completing patterns, and unit conversions. This variety will keep children engaged while not overwhelming them with difficult concepts they may not have encountered yet in the classroom. This book covers the following topics: Simple math riddles Easy math riddles Intermediate math riddles Hard level riddles Challenging math riddles For fun riddles ...And much more Math riddles follow a popular current trend in education known as gamification which seeks to mix learning and fun. If students are having fun while they learn, they will be more motivated to tackle harder subjects and advance their own learning. Even children who are already adept in a subject can benefit from gamification, as it ensures they will not grow bored with the subject and they are always challenging themselves to improve. The challenge of solving riddles and the sense of pride children get from working hard to get a riddle right plays directly into this trend to turn math into a game. Math riddles really work to get your child engaged and personally invested in their own education because they make learning fun. The different difficulties serve as 'levels' for your child to test their knowledge and expand into a better understanding of new concepts. When learning and playing are combined, your child will begin to see their education as something they want to actively participate in rather than something they passively learn in a classroom.

  difficult math riddles with answers: Heard on The Street Timothy Falcon Crack, 2024-08-05 [Warning: Do not buy an old edition of Timothy Crack's books by mistake. Click on the Amazon author page link for a list of the latest editions .] THIS IS A MUST READ! It is the first and the original book of quantitative questions from finance job interviews. Painstakingly revised over 30 years and 25 editions, Heard on The Street has been shaped by feedback from hundreds of readers. With well over 75,000 copies in print, its readership is unmatched by any competing book. The revised 25th edition contains 242 quantitative questions collected from actual job interviews in investment banking, investment management, and options trading. The interviewers use the same questions year-after-year, and here they are with detailed solutions! This edition also includes 267 non-quantitative actual interview questions, giving a total of more than 500 actual finance job interview questions. Questions that appeared in (or are likely to appear in) traditional corporate finance or investment banking job interviews are indicated with a bank symbol in the margin (72 of the 242 quant questions and 196 of the 267 non-quant questions). This makes it easier for corporate finance candidates to go directly to the questions most relevant to them. Most of these questions also appeared in capital markets interviews and quant interviews. So, they should not be skipped over by capital markets or quant candidates unless they are obviously irrelevant. There is also a recently revised section on interview technique based on feedback from interviewers worldwide. The quant questions cover pure quant/logic, financial economics, derivatives, and statistics. They come from all types of interviews (corporate finance, sales and trading, quant research, etc.), and from all levels of interviews (undergraduate, MS, MBA, PhD). The first seven editions of Heard on the Street contained an appendix on option pricing. That appendix was carved out as a standalone book many years ago and it is now available in a recently revised edition: Basic Black-Scholes. Dr. Crack did PhD coursework at MIT and Harvard, and graduated with a PhD from MIT. He has won many teaching awards, and has publications in the top academic, practitioner, and teaching journals in finance. He has degrees/diplomas in Mathematics/Statistics, Finance, Financial Economics and Accounting/Finance. Dr. Crack taught at the university level for over 25 years including four years as a front line teaching assistant for MBA students at MIT, and four years teaching undergraduates, MBAs, and PhDs at Indiana University. He has worked as an independent consultant to the New York Stock Exchange and to a foreign government body investigating wrong doing in the financial markets. He previously held a practitioner job as the head of a quantitative active equity research team at what was the world's largest institutional money manager.
