Numbers Near Multiples Of Ten. It's fairly easy to multiply two numbers that are close to the same multiple of 10. The algorithm for doing it is called “Nikhilam Navatascaramam Dasata.” It is part of a system of algorithms and mnemonics to remember them, collectively known as “Vedic Math”, that was developed by Jagadguru Swami Bharati Krishna Tirthaji Maharaj in the early 20th century. The easiest way to explain the algorithm is to give examples, and explain the algorithm along the way. 7 x 8 First find a suitable “base”. Since 7 and 8 are both close to 10, we'll use 10. Write the difference between the numbers to be muliplied, and the base, off to the right: base 10 7 | -3 x 8 | -2 Multiply the differences. -3 x -2 = 6. Base 10 7 | -3 x 8 | -2 ________ | 6 Now add the difference between the one number to be multiplied and 10, to the other number to be multiplied.
Put the result on the left side of the answer: base 10 7 | -3 x 8 | -2 ________ 5 | 6 7 x 8 = 56 98 x 89 ____ The 87 comes from either 89 + (-2), or 98 + (-11). To make nearly all course materials available free on the World Wide Web. CAMBRIDGE, Mass. -- MIT President Charles M. Vest has announced that the Massachusetts Institute of Technology will make the materials for nearly all its courses freely available on the Internet over the next ten years. He made the announcement about the new program, known as MIT OpenCourseWare (MITOCW), at a press conference at MIT on Wednesday, April 4. President Vest focused on how OpenCourseWare reflected the idealism of the MIT faculty and the core educational mission of MIT in his remarks to print and television reporters.
"As president of MIT, I have come to expect top-level innovative and intellectually entrepreneurial ideas from the MIT community. "I have to tell you that we went into this expecting that something creative, cutting-edge and challenging would emerge. "OpenCourseWare is not exactly what I had expected. "OpenCourseWare looks counter-intuitive in a market driven world. Potential impacts "Am I worried that the OpenCourseWare project will hurt MIT's enrollment? World History : HyperHistory.

© VeerPRZEMYSLAW PRZYBYLSKI Use these techniques to improve your memory. The tools in this section help you to improve your memory. They help you both to remember facts accurately and to remember the structure of information. The tools are split into two sections. Firstly you'll learn the memory techniques themselves. Secondly we'll look at how you can use them in practice to remember peoples names, languages, exam information, and so on. As with other mind tools, the more practice you give yourself with these techniques, the more effectively you will use them. Mnemonics 'Mnemonic' is another word for memory tool. The idea behind using mnemonics is to encode difficult-to-remember information in a way that is much easier to remember. Our brains evolved to code and interpret complex stimuli such as images, colors, structures, sounds, smells, tastes, touch, positions, emotions and language.
Using Your Whole Mind to Remember You can do the following things to make your mnemonics more memorable: Remember Any Number With the Major Memory System. Did you ever want to be able to recite pi up to 22,500 decimal digits? As for me, I never felt attracted to that sort of stuff. But remembering phone numbers, passwords, PINs, birthdays and all sorts of everyday numbers — that’s something I resonate with!
Meet the Major memory system, one of the most powerful techniques around for memorizing numbers. If you think you could use a boost to your memory, or just want to jog your brain a little, here’s a great way to do it. How the Major Memory System Works Our brains are notoriously poor at memorizing numbers. And that’s what the Major system is about: converting abstract, dull numbers into vivid, striking images. The Major Memory System in 3 Steps 1. The heart of the Major system — and the key to convert numbers to images and vice-versa — is a 10-item mnemonic table.
As an example, let’s take the (in)famous number 42. According to the mnemonic table, the digits in the number 42 translate to r and n respectively. 42 gets encoded as rain, then. Free online speed reading software | Spreeder.com.
