The easy way to add and subtract fractions. Multiply crosswise and add to get the top of the answer:2 x 5 = 10 and 1 x 3 = 3. Then 10 + 3 = 13.The bottom of the fraction is just 3 x 5 = 15.You multiply the bottom number together.So: Subtracting is just as easy: multiply crosswise as before, but the subtract: Try a few:

INTRODUCTION Vedic Mathematics is the name given to the ancient system of Mathematics which was rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krsna Tirthaji (1884-1960). According to his research all of mathematics is based on SIXTEEN SUTRA , or word-formulae. For example, 'Vertically and Crosswise` is one of these Sutras. These formulae describe the way the mind naturally works and are therefore a great help in directing the student to the appropriate me

There are a lot of interesting theories in physics. Matter exists as a state of energy, while waves of probability spread throughout the universe. Here are some of the most interesting theories, to my mind, in modern physics (in no particular order, despite the enumeration).Many are in our courses.1) Wave Particle DualityMatter and light have properties of both waves and particles simultaneously. The results of quantum mechanics make it clear that waves exhibit particle-like properties and particles exhibit wave-like properties, depending on the specific experiment. Quantum physics is therefore able to make descriptions of matter and energy based on wave equations t

hi, this is one of the most inspiring stories i have ever come across. do take the pleasue of reading through it. its really inspiringgggggggggggg....... Broken Wing Some people are just doomed to be failures. That's the way some adults look at troubled kids. Maybe you've heard the saying, "A bird with a broken wing will never fly as high." I'm sure that T. J. Ware was made to feel this way almost every day in school. By high school, T. J. was the most celebrated troublemaker in his town. Teachers literally cringed when they saw his name pos

Funny how we can be more worried about what other people think of usthan what we think of ourselves. The paradox of our time in history is that we have taller buildings,but shorter tempers; wider freeways, but narrower viewpoints; we spendmore, but have less; we buy more, but enjoy it less. We have biggerhouses and smaller families; more conveniences, but less time; we havemore degrees, but less sense; more knowledge but less judgment; moreexperts, but more problems; more medicine, but less wellness. We havemultiplied our possessions, but reduced our values. We talk too much,love too seldom, and hate too often. We've learned how tomake a living, but not a life; we'

Did Bhaskar II discover calculus? Bhaskar II was born in Vijapur in the province of Karnataka in 1114 A.D. He wrote Siddhanta-Shiromani in 1150, which became a classical text in Mathematics and Astronomy. The book is divided in four parts: Lilavati deals with arithmetic, Bijaganita with algebra, Ganitadhyaya and Goladhyaya with astronomy. In Siddhanta Shiromani, Bhaskar II defines two kinds of planetary velocities: Sthula gati (average speed) and Sukshma or Tatkaliki gati (instantaneous velocity). The process of finding instantaneous velocity involves the use of differential calculus. There is definite proof that Bhaskar II carried out suc

ROBOTIC SURGERY: A NASA doctor demonstrates the robotic surgeon that was created by NASA. Seattle: Doctors and scientists from the University of Washington will get a glimpse of what it would be like to do remote surgery in space when a portable medical robot they created will be tested next month in an underwater environment designed by NASA to simulate zero gravity. The portable robot, which can be controlled over the Internet by a human surgeon many miles away, is being developed with money from the US Defense Department to be used to treat wounded soldiers on a battlefield, to perform complicated s

1. There is a man who lives on the top floor of a very tall building.Everyday he gets the elevator down to the ground floor to leave thebuilding to go to work.Upon returning from work though, he can only travel half way up in the lift and has to walk the rest of the way unlessit's raining! Why? (This is probably the best known and most celebrated ofall lateral thinking puzzles. It is a true classic. Although there are many possible solutions which fit the initial conditions, only thecanonical answer is truly satisfying. )~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~2.

Sherlock Holmes and Dr. Watson went on a camping trip. After a good meal and a bottle of wine, they lay down for the night, and went to sleep. Some hours later, Holmes awoke and nudged his faithful friend. "Watson, look up at the sky and tell me what you see." Watson replied, "I see millions and millions of stars." "What does that tell you?" Holmes asked. Watson pondered for a minute. "Astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Horologically, I deduce that the time is approximately a quarter past three. Theologically, I can see that God is all-powerful and that

Once upon a time a very strong woodcutter asked for a job in a timber merchant, and he got it. The paid was really good and so were the work conditions. For that reason, the woodcutter was determined to do his best. His boss gave him an axe and showed him the area where he was supposed to work. The first day, the woodcutter brought 18 trees "Congratulations," the boss said. "Go on that way!" Very motivated for the boss? words, the woodcutter try harder the next day, but he only could bring 15 trees. The third day he try even harder, but he only could bring 10 trees. Day after day he was bringing less and less trees. "I must be losing my str

Loss or misuse of constants of integration. The indefinite integral of a function involves an "arbitrary constant", and this causes confusion for many students, because the notation doesn't convey the concept very well. An expression such as "3x2+5x+C" really is supposed to represent an infinite collection of functions -- it represents all of the functions 3x2+5x+7, 3x2+5x+19, 3x2+5x?3.19, etc. plus more functions of the same sort. One of the difficulties, also, is that the same letter "C" is customarily used for all such arbitrary constants; but one computation may involve several different arbitrary constants. It would be more accurate to put s
