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”. 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 Now let's try it with significantly bigger numbers, to see why this is such an advantage. 98 x 89 ____ Since both numbers are close to 100, we will use 100 as our base. 10200 + (-08) = 10192 104 x 98 = 10192

List of unusual deaths This is a list of unusual deaths. This list includes unique or extremely rare circumstances of death recorded throughout history, noted as being unusual by multiple sources. Some of the deaths are mythological or are considered to be unsubstantiated by contemporary researchers. Oxford Dictionaries defines the word "unusual" as "not habitually or commonly occurring or done" and "remarkable or interesting because different from or better than others."[1] Some other articles also cover deaths that might be considered unusual or ironic, including List of entertainers who died during a performance, List of inventors killed by their own inventions, List of association footballers who died while playing, List of professional cyclists who died during a race and the List of political self-immolations.

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?

Shrooms Change Your Life for the Better I've tried shrooms in the past. What the researchers are saying is totally true. Keep in mind, the drug opens up a spiritual pathway, not to be confused with a god(s) thing. For example, when I did try these, I tried them with someone who was a chronic abuser of pot (as in woke up stoned and went to sleep stoned). FYI: I don't recommend taking them.

How to Forecast Weather | Ever wondered how to forecast the weather without actually using instruments? Check the Clouds: Clouds can tell us a lot about the weather. For example, they can tell us if it’s going to be warmer on a particular night by simply being there. Check the Humidity: If you’re one of those people whose hair gets all curly when it gets really humid out, you know exactly what this is about. Check the Animals: Birds only fly in the sky when they expect fair weather ahead. Look at the Rainbow (but only in the west) and look for a Red Sky: If you see one in the west, it means a major storm front is coming. Check the Air: If it smells like a compost heap, expect some rain soon. Check the Moon: Seen any red moons lately? Check the Wind: If you can tell which way the wind is blowing, you can tell if there is a storm approaching. A Few More Ideas: Make a campfire – If the smoke goes straight up, clear skies ahead. Check the grass – if it’s wet and dewy, that means it probably won’t rain.

10 Papers Every Programmer Should Read (At Least Twice) I spent most of yesterday afternoon working on a paper I’m co-writing. It was one of those days when the writing came easy. I was moving from topic to topic, but then I realized that I was reaching too far backward – I was explaining things which I shouldn’t have had to explain to the audience I was trying to reach. When I first started writing, one of the pieces of advice that I heard was that you should always imagine that you are writing to a particular person. It gets your juices going – you’re automatically in an explanatory state of mind and you know what you can expect from your audience. I was doing that, but I noticed that I was drifting. The problem I was experiencing is only getting worse. So, I was thinking about this and trying to not to get too glum. We’ve taken an interesting turn in the industry over the past ten years. Here’s the original list. Most are easy to read but some are rough going – they drop off into math after the first few pages.

Memory Improvement Techniques - Improve Your Memory with MindTools © 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. 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. Unfortunately, a lot of the information we have to remember in modern life is presented differently – as words printed on a page. This section of Mind Tools shows you how to use all the memory resources available to you to remember information in a highly efficient way.
