DISCLAIMER

ABOUT THE GAME KENKEN

MathDoku is a mathematical and logical puzzle based on KenKen and loosely similar to sudoku.

Puzzles can be solved by combining the four main mathematical functions of addition, subtraction, multiplication and division. To train the brain the puzzles are offered without any instruction. There are important keys to be found but no fixed starting place and no method of progression that can be learned as a strategy. The brain is forced to dart between competing theories. It’s impossible to solve puzzles without the scientific process of trial and error and that’s the rationale behind these puzzles.

KenKen was invented by a Japanese mathematics teacher Tetsuya Miyamoto and introduced to The Times via Robert Fuhrer of Nextoy and Chess Champion Dr. David Levy and recognized for its depth and magnitude by The Times features editor, Mr. Michael Harvey. KenKen brain training puzzles are a trademark of Nextoy, LLC. Toy inventor Robert Fuhrer, founder of Nextoy, discovered KenKen (aka KEN-KEN) in Japan as the original books published by educational publisher Gakken Co., Ltd. as Kashikoku naru Puzzle, and has been instrumental in introducing them to the western world.

ABOUT US

This KenKen adventure started in late November 2008.

My girlfriend found the game KenKen in a local newspaper. Having both been fans of sudoku (although she was significantly better than me), we immediately took a liking and interest to this new type of game. We played KenKen games as often as we could and always looked for the local newspaper to play another game, especially when we were at coffee shops where newspapers were plentiful and many times free.

This interest rapidly grew into an obsession. Newspaper versions were not enough. A quick search of the interwebs yielded few results and proved ineffective as KenKen printable versions burned a lot of consumables like paper, ink, and electricity (we’re trying to live a little greener). To ease the addiction, we set out to make our own interactive, online version. And in less than a month the initial site, http://www.webkendoku.com/, was born. Shortly afterwards, in February 2009, we were notified by Robert Fuhrer that the use of “kendoku” in the domain name infringed on their trademark of “KenDoKu “. To avoid any legal disputes, WebKendoku.com closed as we transitioned to this new site. We apologize for the inconvenience and hope you enjoy this site and the game as much as we do.

But, we could not have possibly done it alone.

Hints and tips by Mr Kitty

BD Rating Difficulty ** Enjoyment ****

Hello everyone. Today we have no obscure plants, words, or historical figures, no cricket, and a great mix of clue types with some very smooth surfaces. This was probably my fastest solve of all the Tuesday puzzles I’ve blogged so far, but I’m putting that down to luck because there were definitely a few places where I know I would have been stymied not so long ago. While I’m giving it 2* for difficulty, I don’t have a lot of confidence in that rating and I look forward to hearing what everyone else thought of it. No problems with the enjoyment rating though, since this was a most entertaining tussle with some very clever clue constructions. As usual, I’m not brave enough to suggest a setter, but I do hope that they will drop in later to take credit for it and allow us to thank them in person.

In the hints below the definitions are underlined and the answers will be revealed by clicking on the Mathematical crossword puzzles with answers buttons. Several of crosswordland’s usual suspects are hyperlinked to fuller explanations elsewhere on the site. Please leave a comment telling us how you got on.

HOTHEAD : Split (3,4), the answer might describe a consequence of spending too long in the sun without a hat.

22d Patch up and get married again? (6)

REPAIR : Split (2-4), the answer might mean “getting married again”. Question for the experts: Is there an official name for clues like this and 21d, where the answer must first be split in some way to generate a cryptic correspondence with the part of the clue that isn’t the straight definition?

25d Shock Scot and Ulsterman on vacation (4)

STUN : “On vacation” here refers to what remains when the internal letters of a word are removed. So, we are being instructed here to combine the outer letters of ScoT and UlstermaN. This device is not uncommon over in Toughieland, but previous research suggests that today might be the first time that it’s been used on the back page.

Mathematical crossword puzzles with answers

Thanks to today’s setter for a very enjoyable solve. My favourite clue today was the clever and original 24a, with ticks for 6a, 29a, 5d, 8d, 11d, and 25d. Which clue topped your list?

Accounting Interview Questions and Answers, mathematical questions and answers.#Mathematical #questions #and #answers


How to Ace Your Accounting Interview?

Mathematical questions and answersWhat questions should you expect? How to make a long lasting impression on your interviewers? And what decides the winner at the end?

Simply, how to prepare for this challenging experience, and walk away with a coveted job contract? We try to answer this question on our website that specializes only in accounting interviews. Written by Caren Mayers, Recruitment Consultant at Financial Recruitment Agency HW Search by Matthew Chulaw, Independent Interview Coach. Welcome!

What questions should you expect?

The principal part of your interview will consist either in behavioral questions, or in practical exercises. The interviewers in smaller companies will usually test you with a series of short case studies (VAT calculation, balance sheet reporting, cash flow analysis, etc.), trying to understand whether you can do the job, or just talk about doing it.

In big corporations, however, you can expect a more traditional approach. You will have to deal with personal, behavioral, and technical interview questions, and often also with a personality test. But they will use less case studies, since they will provide you a training if they hire you.

Typical questions added to the mix

In both big and small companies, as well as in recruitment agencies, they will use some typical interview questions to understand your personality, communication skills, and motivation. Why do you want to be an accountant? , What characterize a good accountant? , What do you think is a goal of an accountant in this company? are some of these typical questions.

Other things do also matter

Brilliant interview answers form a foundation stone for your success. But you shouldn t forget that interviewers observe many things, such as your non-verbal communication, your methodology in work, your way of thinking. They try to assess whether you meet the following criteria:

  • Decent computing skills
  • Mathematical skills
  • Responsibility and loyalty
  • Attention to detail
  • Patience

Mathematical questions and answersTry to present yourself as a detail oriented, responsible, motivated, and loyal employee.

List of typical accountant interview questions

Note: Clicking a question will direct you to a separate page where we analyze the particular question and offer sample answers.

However, we suggest you to firstly read this page to the end, so you understand all nuances of accounting interviews, before you start practicing interview answers.

Do the questions differ in various companies?

Obviously, the interview process differs in every company. On the other hand, if they try to recruit a corporate accountant, they will not give the applicants questions intended for managers, or for bank tellers. . . .

Even if they use slightly different questions, the same strategies and attitudes will lead you to a coveted job contract in every single accounting interview. It s just a matter of understanding the way of thinking of the interviewing panel, and what they expect to hear from an ideal candidate for the job.

Mathematical questions and answersAsking questions

Job interview is not a monologue. And it shouldn t become one.

You should ask the employer some questions about their working environment, accounting software, career growth possibilities, next step of the recruitment process. Simply anything sensible, that will show that you care, and want to learn more about your future employer.

Talk of two people

At the end of the day, do not forget that every job interview is just a meeting of two (or more) people You and the interviewer(s). Try to approach it in a way in which you should approach every other meeting show positive attitude, praise the other person, listen to what they have to say, show enthusiasm for the topic of the meeting (getting employment with them).

You should simply try and build a relationship with your interviewers.

Helpful material

We hope that our answers to particular interview questions help you to gain confidence, and prepare for the interview. But if you still find the preparation challenging, you can have a look at our Accountant Interview Guide. The eBook offers brilliant answers to all twenty most common accountant interview questions, practical exercises, winning interview strategies, and much more

I wish you good luck in your interview!

Mathematical questions and answers Mathematical questions and answers

People wrote differently in those days, obviously the vulgar mechanick may be a man and he that is able to reason nimbly and judiciously may be a woman, (and either or both may be children).

for complicated mathematics building on simpler mathematics.

The following examples illustrate the difference between the two approaches to understanding mathematics described above.

You won’t be able to learn how to understand mathematics from abstract principles and a few examples. Instead you need to study the substance of mathematics. I’m hoping that the answers to the following

will illustrate how mathematics is meant to make sense and is built on a logical procession rather than a bunch of arbitrarily conceived rules.

One of the main things that turned me on to mathematics were certain concepts and arguments that I found particularly beautiful and intriguing. I’m listing some of these below even though they may not be frequently asked about. But I’ll hope you’ll enjoy them, and perhaps get more interested in mathematics for its own sake.

Solving Mathematical Problems

The most important thing to realize when solving difficult mathematical problems is that one never solves such a problem on the first attempt. Rather one needs to build a sequence of problems that lead up to the problem of interest, and solve each of them. At each step experience is gained that’s necessary or useful for the solution of the next problem. Other only loosely related problems may have to be solved, to generate experience and insight.

Students (and scholars too) often neglect to check their answers. I suspect a major reason is that traditional and widely used teaching methods require the solution of many similar problems, each of which becomes a chore to be gotten over with rather than an exciting learning opportunity. In my opinion, each problem should be different and add a new insight and experience. However, it is amazing just how easy it is to make mistakes. So it is imperative that all answers be checked for plausibility. Just how to do that depends of course on the problem.

There is a famous book: G. Polya, How to Solve It , 2nd ed., Princeton University Press, 1957, ISBN 0-691-08097-6. It was first published in 1945. This is a serious attempt by a master at transferring problem solving techniques. Click here to see an html version of Polya’s summary.

The main thing that keeps mathematics alive and interesting of course are unsolved problems. Many open problems that are important in the contemporary view are hard just to understand. But here are

for which you can form your own conjectures. The word simple in this context means that the problem is easy to state and the question is easy to understand. It does not mean that the problem is easy to solve. In fact all of these open problems are difficult. (That’s why they are unsolved, it’s not that nobody tried!)

Acquiring Mathematical Understanding

Since this is directed to undergraduate students a more specific question is how does one acquire mathematical understanding by taking classes? But that does not mean that classes are the only way to learn something. In fact, they often are a bad way! You learn by doing. For example, it’s questionable that we should have programming classes at all, most people learn programming much more quickly and enjoyably by picking a programming problem they are interested in and care about, and solving it. In particular, when you are no longer a student you will have acquired the skills necessary to learn anything you like by reading and communicating with peers and experts. That’s a much more exciting way to learn than taking classes!

No problems with the enjoyment rating though, since this was a most entertaining tussle with some very clever clue constructions. As usual, I’m not brave enough to suggest a setter, but I do hope that they will drop in later to take credit for it and allow us to thank them in person.

ABOUT THE GAME KENKEN

MathDoku is a mathematical and logical puzzle based on KenKen and loosely similar to sudoku.

Puzzles can be solved by combining the four main mathematical functions of addition, subtraction, multiplication and division. To train the brain the puzzles are offered without any instruction. There are important keys to be found but no fixed starting place and no method of progression that can be learned as a strategy. The brain is forced to dart between competing theories. It’s impossible to solve puzzles without the scientific process of trial and error and that’s the rationale behind these puzzles.

KenKen was invented by a Japanese mathematics teacher Tetsuya Miyamoto and introduced to The Times via Robert Fuhrer of Nextoy and Chess Champion Dr. David Levy and recognized for its depth and magnitude by The Times features editor, Mr. Michael Harvey. KenKen brain training puzzles are a trademark of Nextoy, LLC. Toy inventor Robert Fuhrer, founder of Nextoy, discovered KenKen (aka KEN-KEN) in Japan as the original books published by educational publisher Gakken Co., Ltd. as Kashikoku naru Puzzle, and has been instrumental in introducing them to the western world.

ABOUT US

This KenKen adventure started in late November 2008.

My girlfriend found the game KenKen in a local newspaper. Having both been fans of sudoku (although she was significantly better than me), we immediately took a liking and interest to this new type of game. We played KenKen games as often as we could and always looked for the local newspaper to play another game, especially when we were at coffee shops where newspapers were plentiful and many times free.

This interest rapidly grew into an obsession. Newspaper versions were not enough. A quick search of the interwebs yielded few results and proved ineffective as KenKen printable versions burned a lot of consumables like paper, ink, and electricity (we’re trying to live a little greener). To ease the addiction, we set out to make our own interactive, online version. And in less than a month the initial site, http://www.webkendoku.com/, was born. Shortly afterwards, in February 2009, we were notified by Robert Fuhrer that the use of “kendoku” in the domain name infringed on their trademark of “KenDoKu “. To avoid any legal disputes, WebKendoku.com closed as we transitioned to this new site. We apologize for the inconvenience and hope you enjoy this site and the game as much as we do.

But, we could not have possibly done it alone.
