Rhind Papyrus
https://www.cut-the-knot.org/arithmetic/RhindPapyrus.shtml
The Rhind Mathematical Papyrus [ Midonick. Pp 706-732, Fauvel. Much of the Rhind Papyrus deals with proportional reasoning and multiplication by doubling. I'll give a couple of examples based on [ Midonick. Divide 7 loaves among 10 men. Each man receives 2/3 1/30. 2 2/3 1/10 1/30. Total of 7 loaves, which is correct. The expression "2/3 1/30" should be understood as the sum of terms involved. In the modern notations:. 2/3 1/30 = 21/30 = 7/10,. 1 1/3 1/15 5 1/2 1/10. 6 10/30 2/30 15/30 3/30. A reproductio...

Odd Coin Problems: the 120 marble problem - five weighings
https://www.cut-the-knot.org/blue/OddCoinProblems.shtml
Here is my solution. (A shorter variant. Is also available.) You might want to skip the early part, as it is for those not "up to date" on the general coin weighing problems. Different weight coin (marble - ball - etc.) problems using a pan balance to discover the odd item. This solution is directed at problems wherein the odd coin is either heavier or lighter than the others, but we do not know which. I will call this the "Odd Weight Coin" problem. First, some fundamentals:. I will call this Method A:.

Education, of the occasional causes of melancholy, may justly challenge the next place (AB: after nursing), for if a man escape a bad nurse, he may be undone by evil bringing up. The Anatomy of Melancholy. New York Review Books,. 2001, p. 333 (The First Partition). Can I do anything? What's in a proof? Is math around us? Need math be relevant?

Three Similar Triangles
https://www.cut-the-knot.org/Curriculum/Geometry/SimilarTriangles.shtml
What is that about? 1 June 2015, Created with GeoGebra. This is what the applet purports to show. Take any two similar triangles ABC and A'B'C' whose vertices are traversed in the same direction, either both clockwise or both counterclockwise. Divide AA', BB', CC' in equal proportions and connect the resulting points. The new triangle will be similar the the given two. Think of the vertices as complex numbers. Two triangles ABC and A'B'C' are similar iff, say,. B - A)/(C - A) = (B' - A')/(C' - A'). Assum...

When I use a word. it means just what I choose it to mean". Vai quedando de lado. É inevitable. Como a LOMCE non se implantou en 4º de ESO, aínda podo traballar mellor que cando teña unha reválida na caluga. Polo que este ano decidín comezar seriamente por eses contidos comúns. E que mellor campo que a Combinatoria, que dentro das Matemáticas elementais ten probablemente a mellor ratio dificultade/sofisticación. Cantos números entre 1 e 1000 son múltiplos de 3 e 5? Cantos son múltiplos de 3 pero non de 5?
