	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 help Chris Fisher and Harley Weston lui répond.
	The sum of the angles of a triangle		2016-02-24

	Archimedes, Euclid and "Circular Reasoning"		2015-11-15
		Ron pose la question : I have read about Archimedes and his work with sphere in cylinder and cone in cylinder and the volume relationships. Did he or any others also extend this to regular based polygon based regular like pillars, and columns? The ratio of 1/3 to 1 whole holds true with all regular based columns as example: a regular pyramid having a regular hexagon base inside a regular hexagon column of equal height. Chris Fisher lui répond.

	I want to learn math		2007-08-07
		Maria pose la question : Hello. I am 16-years-old, and I would like to learn as much mathematics as I can and to really understand it. I would like to know what people mean when they say things like "thinking mathematically" or "math is equally beautiful and true". However, I'm not sure where to start. :-) What do you think of going back to the beginning and working my way through Euclid? Your help would be very much appreciated. Thank you. Harley Weston 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. Thanks Penny Nom lui répond.

		Geecee pose la question : At a local village gala, the entire population turned up, 500 people. The event raised £3,000. Tickets were priced as follows: £7.48 men, £7.12 women and £0.45 children. How many children were there? Stephen La Rocque lui répond.
	Absolute Value vs. Standard Deviation ?		2006-04-24
		Sonia pose la question : Why we don't just take the average of the absolute value of difference scores (use the mean deviation) to describe variability instead of calculating the standard deviation? Claude Tardif lui répond.
	Ratio and proportion		2004-04-02
		Kenneth pose la question : The terms of a ratio in a proportion are often expressed as a is to b as c is to d. Example: 2/4 = 6/12 this proportion represents that 2 is to 4 as 6 is to 12. What does the "a is to b as c is to d" really represent or indicate in ratios? Claude Tardif lui répond.
	Non-euclidean geometry		2003-12-08

	Can a square be considered a rectangle?		2003-02-27
		Carla pose la question : Can a square be considered a rectangle? (since opposite sides are same length and parallel) Would a regular hexagon or octagon be considered a parallelogram since its opposite sides are parallel? or does a parallelogram HAVE to have only 4 sides? Penny Nom lui répond.

		Rob pose la question : I'm a student at St. John's College in Santa Fe New Mexico, are school is devoted to the great books and we're now reading Euclid's Elements in english and Attic Greek.

	Euclidean Math puzzle		2000-01-24
		Margaret Matthews pose la question : (Check out this web-site: Simeon's Triangle Puzzle ) I have tried to figure out how this could be, because everything I know about it tells me it can't be. However, I can't seem to make it NOT work. Two right angle triangles. They are each cut up into four identical pieces. In the first, all the pieces fit together so that there are NO empty spaces; in the second, presumed to be identical in size to the first, the pieces are slightly rearranged, and now, there IS a space in the triangle. Patrick Maidorn and Claude Tardif lui répond.
