For example: if you arrange the number along a circle and put the number 142857 at the centre all the numbers taken cyclically, starting with 1, are fully divisible by 37. Whatever the starting point of this number, it remains fully divisible by 37. what is more, the number can be formed by taking the digits clockwise as well as anti-clockwise..This I call "full cyclic divisibility". In many cases, only clockwise cyclic divisibility is possible. But I have not come across a case where ONLY anti-clockwise divisibility occurs. Thus clockwise cyclic divisibility seems to be favoured. Could this be construed as a sign of chirality in mathematics?..Answered by Chris Fisher. 128/(-16)/(-2) 2015-01-28 From jackie:128/(-16)/(-2) I was wondering if you can show me how to work this question outAnswered by Harley Weston.

Turning Fractions into Decimals 1999-01-16 From Lynn:How do you do it step by stepAnswered by Jack LeSage. Indeterminate forms 1998-12-11 From R. Dixon:What is the correct evaluation of infinity/0 ? I've checked three different math sites. One says definitively, that infinity/0 is "not" possible. Another states that infinity/0 is one of the indeterminate forms having a large range of different values. The last reasons that infinity/0 "is" equal to infinity.Answered by Walter Whiteley and Harley Weston. Fraction division 1998-11-18 From Brett Darrough:I am needing specific examples that illustrate division of fractions with In-depth understanding. I am enrolled in a CGI (cognitivly guided instruction) course which is trying to develop a method of teaching fraction division with understanding. Most people invert and multiply to obtain a correct answer. Why? I would like help in understanding this method that includes pictures and algorithms that illustrate reasoning and depend on understanding.Answered by Jack LeSage and Harley Weston. The Largest Factor 1998-03-15 From Senthuran Nadarajah:When each expression is evaluated for different values of n, the answers will differ. For each expression, find largest natural number that will divide the result for all natural number values of n. n^5 - 5n^3 + 4nAnswered by Harley Weston. The Factor Theorem 1998-01-18 From Dhruv Bansal:Hi, I'm a ninth grade student doing a math project for school. I'm trying to learn about various ways of solving 3rd and 4th degree polynomial equations using the remainder theorem, the factor theorem, and synthetic division. The books I have all mention x - r, which I know nothing about, not even how to get it. I would really appreciate any information on this. Thanks. Dhruv BansalAnswered by Penny Nom. Division by a fraction. 1997-11-21 From Roger Marchegiano:I am interested in a solution to the following extra credit problem for my son in Geometry. We have been unable to produce a satisfactory response: Show a geometric representation of the division of fractions algorithm, (When you divide fractions you multiply the numerator by the reciprocal of the denominator).Answered by Penny Nom. The Division Bracket. 1997-04-09 From Judy Riley:A fellow teacher recently asked if I remembered the exact word for a division bracket (not the symbol with dots, the horizontal line in a fraction, or a solidus). I couldn't. Can you help?Answered by Walter Whiteley and Harley Weston. Division by zero 1997-02-14 From Linda Hood:I am a college student and have been asked to explain and figure out why we can't divide by zero.Answered by Chris Fisher. Priority of operations 1996-11-04 From Wallace:What is the answer to this problem? Let x=-2 and y=3. Evaluate 12x / 2y (if the old division sign is used).Answered by Chris Fisher. Could you tell me the name for the bar in a division problem? 1996-10-21 From Linda:Could you tell me the name for the bar in a division problem. Not the line with dots on either side but the line that divides the two numbers? My name is Linda. I am asking for my niece who is in 8th grade.Answered by Chris Fisher. Division 2010-03-10 From lucas:bonjour je suis eleve de 6 eme je bloque sur ce petit probleme Nat a fait une division,elle ecrit 4568=23*198,608+reste que vaut ce reste? merci d'avance lucasAnswered by Claude Tardif.
