Sum may refer to:
As an acronym, SUM may refer to:
A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.
In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

This is the second half of a lesson, watch the first half here: http://youtu.be/yudhkUUzAgY This is a well-known and hugely controversial result. The "proof" I've demonstrated is not the only way to show it - there are far more sophisticated and convincing ways to do it - but suffice to say that I went through it to raise questions and provoke thought rather than to make a statement about its validity or otherwise! Hope it makes you think.

The Mathologer sets out to make sense of 1+2+3+ ... = -1/12 and some of those other notorious, crazy-looking infinite sum identities. The starting point for this video is the famous letter that led to the discovery of self-taught mathematical genius Srinivasa Ramanujan in 1913 (Ramanujan is the subject of the movie "The man who knew infinity" that just started showing in cinemas.) Find out about how these identities come up in Ramanujan's work, the role of "just do it" in math, the rules for adding infinite sums on Earth and other worlds, and what all this has to do with the mathematical super star the Riemann Zeta function. You can download the jpeg of Ramanujan's letter to Hardy that I put together for this video here: http://www.qedcat.com/misc/ramanujans_letter.jpg (quite large) You c...

For LIMITS at a FINITE VALUE (not at infinity), jump to the video: http://youtu.be/hewJikMkYFc. 1) For a POLYNOMIAL or CONSTANT in the limit expression: the limit of a CONSTANT (just a finite number like 3), as x approaches infinity or negative infinity, will just be equal to that same constant number.

Our goal in this lecture is to prove that expectation of a sum of two random variables equals to a sum their expectations. Consider the following two random experiments (sample spaces) and random variables defined on their elementary events. Ω1=(E1,E2,...,Em ) with corresponding measure of probabilities of these elementary events P=(P1,P2,...,Pm ) (that is, P(Ei )=Pi - non-negative numbers with their sum equaled to 1) and random variable ξ defined for each elementary event as ξ(Ei) = Xi where i=1,2,...m Ω2=(F1,F2,...,Fn ) with corresponding measure of probabilities of these elementary events Q=(Q1,Q2,...,Qn ) (that is, Q(Fj )=Qj - non-negative numbers with their sum equaled to 1) and random variable η defined for each elementary event as η(Fj) = Yj where j=1,2,...,n Separately, the expe...

We discuss various uses of infinite series in the 17th and 18th centuries. In particular we look at the geometric series, power series of log, the Gregory-Newton interpolation formula, Taylor's formula, the Bernoulli's, Eulers summation of the reciprocals of the squares as pi squared over 6, the harmonic series, product expansion of sinx, the zeta function and Euler's product expansion for it, the exponential function, complex values and finally the circular functions too!
Starting from addition and subtraction that you already understand, I describe how to simplify, read, and use the shorthand of math. There is a mix of explaining and practicing, moving from two numbers to 5 or 6 numbers.
This ain't Sesame Street. The Rankin Lectures 2008, My Favorite Numbers, were given by John Baez of the University of California at Riverside. Baez is well-known for, among other things, his long-running web column This Week's Finds in Mathematical Physics and the research blog The n-Category Café. The numbers 12 and 24 play a central role in mathematics thanks to a series of "coincidences" that is just beginning to be understood. One of the first hints of this fact was Euler's bizarre "proof" that 1 + 2 + 3 + 4 + ... = -1/12 which he obtained before Abel declared that "divergent series are the invention of the devil". Euler's formula can now be understood rigorously in terms of the Riemann zeta function, and in physics it explains why bosonic strings work best in 26=24+2 dimensions...
In this film Stephen Hawking, James Hartle and Thomas Hertog explain their model of the early universe: The No Boundary Proposal. In the 1960’s and 70’s Hawking and Penrose showed that according to classical general relativity, given some minimal assumptions the origin of an expanding universe is a singularity: a point of infinite density and spacetime curvature. But this and other singularity theorems do not take into account the strange world of quantum mechanics. So in the 1980’s Hawking and collaborators started to build a model of the big bang that included quantum effects.The result is the No Boundary Proposal, a model that may be able to explain some of the deepest mysteries of the cosmos such as, is there a multiverse? how is there an arrow of time and what really happened a the bi...
