Pi Cubed is a visual math application for the iPhone / iPod touch that lets you perform calculations as you would on a piece of paper. By using an animated, touch-based interface, even the most complex mathematical expressions can be entered and instantly evaluated. These expressions are typeset as they would be in a textbook or on a blackboard. Calculations are displayed with up to 34 digits of decimal precision. Additionally, a library of over 150 equations ships with the application.

"Several of our classes involve students using mathematical expressions, but there was no way for us to automatically check this work. The stated solution to a problem may be x+y, but if a student answers y+x, our system needs to understand that this is also correct." "sympy, an open source Python library for symbolic mathematics," is proposed as a solution.

CK-12 Foundation's Basic Algebra, Volume 1 Of 2 FlexBook covers the following six chapters:Expressions, Equations, and Functions - covers the relationships among expressions, equations, and functions when variables are present. Also explored is how these ideas can be shown on graphs. Properties of Real Numbers - covers various forms that rational numbers can assume, including fractions, integers, and square roots. Also considered are different operations for manipulating rational numbers. Linear Equations - introduces students to methods of solving simple equations involving variables. Also covered are ratios, scale, and the percent equation. Graphing Linear Equations and Functions - provides students with a more in-depth understanding of equations by introducing coordinate plane graphing concepts such as intercepts and slope. Writing Linear Equations - focuses on writing various forms of equations based upon real-world data and already existing lines. Students will also learn about predicting data using a fitted line. Linear Inequalities and Absolute Value; An Introduction to Probability - covers operations of inequalities, including addition, subtraction, multiplication and division. These principles are then applied to absolute value and probability.

LOG IN February 22, 2012 at 2pm Eastern US time: http://tinyurl.com/math20event During the event, John Mason will lead a conversation about multiplication as scaling, and answer questions about his books, projects and communities. All events in the Math Future weekly series: http://mathfuture.wikispaces.com/events The recording will be at: http://mathfuture.wikispaces.com/JohnMason Your time zone: http://bit.ly/wQYN1Y Event challenge! What good multiplication tasks about scaling do you know? Share links and thoughts! John writes about elastic multiplication: "It is often said that 'multiplication is repeated addition' when what is meant is that 'repeated addition is an instance of multiplication'. I have been developing some tasks which present 'scaling as multiplication' based around familiarity with elastic bands. Participants would benefit from having an elastic (rubber) band to hand which they have cut so as to make a strip; wider is better than thinner if you have a choice." About John Mason John Mason has been teaching mathematics ever since he was asked to tutor a fellow student when he was fifteen. In college he was at first unofficial tutor, then later an official tutor for mathematics students in the years behind him, while tutoring school students as well. After a BSc at Trinity College, Toronto in Mathematics, and an MSc at Massey College, Toronto, he went to Madison Wisconsin where he encountered Polya's film 'Let Us Teach Guessing', and completed a PhD in Combinatorial Geometry. The film released a style of teaching he had experienced at high school from his mathematics teacher Geoff Steel, and his teaching changed overnight. His first appointment was at the Open University, which involved among other things the design and implementation of the first mathematics summer school (5000 students over 11 weeks on three sites in parallel). He called upon his experience of being taught, to institute active-problem-solving sessions, w

Expressing a circle in a standard form expression is defined standard equation of a circle. Imagining a circle in a plane at a particular distance from both axis of the Cartesian coordinate system is the standard form of the circle.

In Educator's Algebra I course, instructor Dr. Grant Fraser walks you through the building blocks of mathematics, starting from Functions, Graphs, and Inequalities, to Factoring, Polynomials, and Rational Expressions. Utilizing his 27 years of teaching experience, UCLA educated (Ph.D and B.S.) Professor Fraser carefully explains each concept from multiple angles to ensure learners of any math ability can master Algebra. Dr. Fraser finishes off every idea with a reinforcing example in addition to the four worked-out video examples and things to remember at the end of each lecture.

Influence of math and numbers and counting on musical composition, performance and expression

"This is a rather unusual structure for organizing mathematical content, but offers an exciting opportunity for teachers across the nation and abroad to exchange ideas and discuss what they teach. This Wiki will address the underlying central concepts and propose activities that also provide rich opportunity to engage students in the Mathematical Practices. "

"Developing a 21st Century Global Library for Mathematics Research discusses how information about what the mathematical literature contains can be formalized and made easier to express, encode, and explore. Many of the tools necessary to make this information system a reality will require much more than indexing and will instead depend on community input paired with machine learning, where mathematicians' expertise can fill the gaps of automatization. This report proposes the establishment of an organization; the development of a set of platforms, tools, and services; the deployment of an ongoing applied research program to complement the development work; and the mobilization and coordination of the mathematical community to take the first steps toward these capabilities. The report recommends building on the extensive work done by many dedicated individuals under the rubric of the World Digital Mathematical Library, as well as many other community initiatives. Developing a 21st Century Global Library for Mathematics envisions a combination of machine learning methods and community-based editorial effort that makes a significantly greater portion of the information and knowledge in the global mathematical corpus available to researchers as linked open data through a central organizational entity-referred to in the report as the Digital Mathematics Library. This report describes how such a library might operate - discussing development and research needs, role in facilitating discover and interaction, and establishing partnerships with publishers."

Definition of the exponential form. A basic example to understand the system of expressing any number into exponential form on the basis of another number.

"The focus of this digitally mediated learning activity centers on the mathematics department in the Easton and Redding (ER9) school district in Connecticut. Currently, ER9 teachers have technology in the classroom, but many teachers have expressed uncertainty about how to implement this technology in their classrooms. Based on the foundations of the constructivist learning theory, math teachers will learn how technology fits into the student learning cycle. Interested teachers will form a community of practice (CoP) to learn about and apply engaging technology in the classroom. Some technologies discussed include game-based learning, mobile/Web 2.0 apps such as Prezi, Animation and Edmodo. As a result of this technology CoP, teachers will learn to implement at least one new technology into their classroom and engage in communication between CoP members using MOODLE. "

With Glean PEMDAS (Please Excuse My Dear Aunt Sally), we present a math learning environment to help teachers extend students' understanding of order of operations concepts.

With Glean PEMDAS (Please Excuse My Dear Aunt Sally), we present a math learning environment to help teachers extend students' understanding of order of operations concepts. Glean PEMDAS can be used to introduce Order of Operations, and is best applied to critical inquiry about application of order.
