 The difference between the ares of two rectangles 2016-06-09 Ingrid pose la question :I am trying to help my son with an area question. I have the answer, from the solutions, but I cannot figure out how to teach him. Question: Two rectangles have lengths 13cm and 19cm respectively. Their total area is 376cm squared. If both their widths are whole numbers, what is the difference in their areas? I know that this is solvable once I determine the widths of the rectangles , but how do I go about finding that? Thanks for your helpChris Fisher and Harley Weston lui répond. A procedure for finding a square root 2015-08-27 Tracey pose la question :Is there a method/process to determine the square root of a large number? For example, Tiananmen Square's area is 396 900m sq., what is the side length? Thank you, TraceyHarley Weston lui répond.

Discovering the incircle of an irregular polygon 2007-05-25 Joaquim pose la question :I've been searching in some books and many websites, but I couldn't find a formula or algorithm for discovering the incircle of an irregular polygon, could you please help me?Walter Whiteley lui répond. Greatest common divisor 2007-03-14 Marie pose la question :How do I prove this? Let h be the greatest common divisor of the positive integers a and b. Show that there exist integers p and q (not necessarily positive) such that pa + qb = h. ThanksPenny Nom lui répond.

Reduce 79,537/3,623,420 2001-12-13 Eliana pose la question :How do you reduce 79,537/3,623,420.Claude Tardif lui répond. A calculation with 6 numbers 2001-06-16 Edwin pose la question :I'm asked to come with, and program (in Ansi -C) an algorithm that calculates all the possible results of a calculation with 6 numbers and one result. For example: I want all calculations with the numbers 3, 3, 8, 8, 2, 9, and with a result of 786. all numbers may be used once, arithmetical operations allowed are + - / *, fractions are not allowed. The problem here is what is a fast method to do this (i.e. what's algorithm that can to this).Claude Tardif lui répond. Why does division start from the left? 2000-05-24 Salil Dave pose la question :Addition, subtraction and multiplications start with right most digit and proceed left, but division starts from left-most digits and goes right ... why? Harley Weston lui répond. Algorithms for roots 1996-02-22 Charles Hewitt pose la question :I have seen an algorithm for finding the square root of numbers. Are there similar such algorithms for higher roots?Harley Weston lui répond. Prime numbers 1996-02-22 Charles Hewitt pose la question :I would apprecaite it if you could share with me any algorithm to determine whether a number is prime.Penny Nom lui répond.
