TeX TeX (/ˈtɛx/ or /ˈtɛk/, see below) is a typesetting system designed and mostly written by Donald Knuth[1] and released in 1978. Together with the Metafont language for font description and the Computer Modern family of typefaces, TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using a reasonably minimal amount of effort, and to provide a system that would give exactly the same results on all computers, at any point in time.[2] TeX is a popular means by which to typeset complex mathematical formulae; it has been noted as one of the most sophisticated digital typographical systems in the world.[3] TeX is popular in academia, especially in mathematics, computer science, economics, engineering, physics, statistics, and quantitative psychology. It has largely displaced Unix troff, the other favored formatter, in many Unix installations, which use both for different purposes.

Mini Folded Paper Stars Who doesn’t love a project with a little magic? Today’s paper art activity, Mini Folded Paper Stars has a reveal that is definitely worth waiting for! Mini Folded Paper Stars are perfect for a rainy afternoon stuck inside, they may add a little brightness to your family’s creative day! This project is great for children ages 7+ but younger children can definitely take part by decorating them and having an adult or older sibling assist them in the cutting and folding process. Like most of the paper projects on Babble Dabble Do, Mini Folded Paper Stars use a minimum of materials. You can make them using regular copy paper but for a sturdier star I recommend printing the template on cardstock.

There’s one key difference between kids who excel at math and those who don’t — Quartz “I’m just not a math person.” We hear it all the time. And we’ve had enough. Solutions and Templates What is a tangram and what is the purpose of a tangram? Tangrams are ancient, truly fascinating Chinese Puzzles, made up of seven movable geometrical shapes, with which you can create thousands of pictures and designs. Learn to make your own, the easy way. The purpose of this puzzle is to use all seven pieces or tans to create a picture or design. The ancient rules dictate that the pieces must lie flat, they must touch and they are not allowed to overlap. Another fun activity is to solve puzzles - this means you take a tangram picture/image and figure out how the shapes were placed to create that image - sounds easier than it is.

Manual of Style The Manual of Style (often abbreviated MoS or MOS) is a style guide for all Wikipedia articles. This is its main page, covering certain topics (such as punctuation) in full, and presenting the key points of others. Subpages, linked via this page's menu and listed at Wikipedia:Manual of Style/Contents, provide detailed guidance on some topics. The Manual of Style documents Wikipedia's house style. LaTeX LaTeX (/ˈlɑːtɛx/ LAH-tekh or /ˈleɪtɛx/ LAY-tekh[1] styled as LaTeX, and a shortening of Lamport TeX) is a word processor and document markup language. It is distinguished from typical word processors such as Microsoft Office and LibreOffice in that the writer uses plain text as opposed to formatted text, relying on markup tagging conventions to define the general structure of a document (such as article, book, and letter), to stylise text throughout a document (such as bold and italic), and to add citations and cross-referencing. A TeX distribution such as TeXlive or MikTeX is used to produce an output file (such as PDF or DVI) suitable for printing or digital distribution. LaTeX is widely used in academia.[3][not in citation given][4] LaTeX can be used as a standalone document preparation system, or as an intermediate format. In the latter role, for example, it is often used as part of a pipeline for translating DocBook and other XML-based formats to PDF.

Multi Digit Multiplication Strategies - Mr Elementary Math Look at the problem below and think about how your students would respond to the two questions: What is the value of the 2?Why should we place a 0 in this space? If your students answer the questions by saying, “the 2 is worth 2,” or “I placed the 0 in that area because I was always told to move it down,” consider the idea that the student(s) do not fully understand the concept of multiplying multi digit numbers.

Troll pi explained @ Things Of Interest Here's the "Troll Pi" or "Pi equals 4" image. Here's the breakdown, as simple as I can make it. All of the following facts are true: Panels one to four describe a sequence of curves. (Here, "curve" is a generic term referring to any continuous line, be it straight or crooked or curved.)Each curve in the sequence has a well-defined length of exactly 4. These facts are also true: DéTECTIVE DES + ET DES - (SMART BOARD/TBI/TNI) <div class="deployment_message_block"><span> Hi, You need to enable javascript on your browser to use TpT.&nbsp; <a href=" target="_blank">See how this improves your TpT experience</a>. </span></div> ABOUT US | BLOG | FAQs & HELP

Manual of Style (linking) Linking through hyperlinks is an important feature of Wikipedia. Internal links are used to bind the project together into an interconnected whole. Interwiki links bind the project to sister projects such as Wikisource, Wiktionary, and Wikipedia in other languages; and external links bind Wikipedia to the World Wide Web. Appropriate links provide instant pathways to locations within and outside the project that are likely to increase readers' understanding of the topic at hand. When writing or editing an article, it is important to consider not only what to put in the article, but what links to include to help the reader find related information, as well as which other pages should carry links to the article. Care should be taken to avoid both underlinking and overlinking, as described below.

The Beauty of Mathematics: A Visual Demonstration of Math in Everyday Life This lovely video short from Yann Pineill and Nicolas Lefaucheux of Paris video production agency Parachutes succinctly demonstrates the underlying mathematics behind everyday occurrences in the format of a triptych. On the left we see the mathematical equation, in the middle a mathematical model, and on the right a video of such things as snowflakes, wind, sound, trees and magnetism. The video begins with the following quote: “Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” —Bertrand Russell Best viewed full screen.

The life and numbers of Fibonacci Fibonacci is one of the most famous names in mathematics. This would come as a surprise to Leonardo Pisano, the mathematician we now know by that name. And he might have been equally surprised that he has been immortalised in the famous sequence – 0, 1, 1, 2, 3, 5, 8, 13, ... – rather than for what is considered his far greater mathematical achievement – helping to popularise our modern number system in the Latin-speaking world.
