This must be a nonnegative integer or None.ensure (optional) – if \(N\) is the minimum number of terms needed for the specified order and degree and len(data) is less than N+ensure, raise an error. An error is raised in the following situations: Ansatz and linear algebra. Note This is a low-level method. Sage: K = GF(1091); R. A Different Kind of Multiplication. It is often said that an important advantage of the decimal notation over the Roman one is that makes multiplication of numbers much easier.

A Different Kind of Multiplication

Adding CLXXVII to XXIII may be relatively straightforward--but how about multiplying the two? It is indeed easier to multiply these as decimal numbers 177 by 23, but the Romans also had a multiplication method of their own. Mathematical Modelling. These virtual math manipulatives support teachers to model abstract mathematical concepts for deeper student comprehension.

Mathematical Modelling

Similar to manipulatives that have been used for decades by teachers in classrooms, these online math manipulatives for elementary school classrooms offer numerous advantages while retaining the benefits of the classic manipulatives. According to Moyer, Niezgoda, and Stanley (2005): “Virtual manipulatives are uniquely suited for teaching mathematics with young children. - CASIO CAS Graphic Calculator. GReGAS Atlas.

Trinity College Cambridge. Use This Quick Trick to Speed Up Long Division. If you’ve ever seen the Japanese trick for multiplying using lines, you know that doing math by hand doesn’t have to mean doing it the old-fashioned way.

Use This Quick Trick to Speed Up Long Division

If long division always confused you or you simply want to try something new, this trick might be for you. Start by choosing a number to divide by another: We’re going to try 145,824 divided by 112. Scientific Computing: An Introductory Survey. Lecture Slides.

The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons.

from Wolfram MathWorld

There are exactly five such solids (Steinhaus 1999, pp. 252-256): the cube, dodecahedron, icosahedron, octahedron, and tetrahedron, as was proved by Euclid in the last proposition of the Elements. The Platonic solids are sometimes also called "cosmic figures" (Cromwell 1997), although this term is sometimes used to refer collectively to both the Platonic solids and Kepler-Poinsot solids (Coxeter 1973). The Platonic solids were known to the ancient Greeks, and were described by Plato in his Timaeus ca. 350 BC. In this work, Plato equated the tetrahedron with the "element" fire, the cube with earth, the icosahedron with water, the octahedron with air, and the dodecahedron with the stuff of which the constellations and heavens were made (Cromwell 1997).

Wang tile - Wikipedia. This set of 11 Wang tiles will tile the plane but only aperiodically.

Wang tile - Wikipedia

Example of Wang tessellation with 13 tiles. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. Domino problem[edit] The Clay Mathematics Institute. ZbMATH - the first resource for mathematics. Angles on Google Drawings.webm.

From the Fun Fact files, here is a Random Fun Fact, at the Advanced level: The traditional proof that the square root of 2 is irrational (attributed to Pythagoras) depends on understanding facts about the divisibility of the integers.

A Random Math Fun Fact!

Odd Numbers in Pascal's Triangle. Pascal's Triangle has many surprising patterns and properties. For instance, we can ask: "how many odd numbers are in row N of Pascal's Triangle? " For rows 0, 1, ..., 20, we count: row N: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 odd #s: 1 2 2 4 2 4 4 8 2 4 04 08 04 08 08 16 02 04 04 08 04. Sums of Two Squares Ways. In the Fun Fact Sums of Two Squares, we've seen which numbers can be written as the sum of two squares. For instance, 11 cannot, but 13 can (as 32+22). Fibonacci GCD's, please. Fibonacci numbers exhibit striking patterns. Here's one that may not be so obvious, but is striking when you see it.

Recall the Fibonacci numbers: n: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,... Numberphile - Videos about Numbers and Stuff. - Play maths, love maths. Physics & Maths Tutor. Learn Math.

According to legend, the Ancient Greek Pythagoras was once walking on the streets of Samos, when the sounds of blacksmiths’ hammering suddenly gave him an epiphany.

Pythagoras rushed into the shop and, as he analyzed mathematically the shapes of the blacksmiths’ hammers, he laid the foundations of music that today’s Rihanna, Shakira and others are building upon. Wait a minute… Are you talking about the guy from the Pythagorean theorem? I am. And despite what you’ve learned at school, this Pythagorean theorem is absolutely not Pythagoras’ greatest idea — most notably because he probably wasn’t even the one who came up with the Pythagorean theorem.
