VEDIC MATH

It is an ancient system of mathematics that was rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krishna Tirthaji (1884-1960). It is based on 16 sutras and 13 sub-sutras or word-formulae. The accent is on the natural working of the mind and a methodical approach to any calculation. It allows for mental calculations through some simple methods and allows ample scope for innovation in the sense that you can invent your own method. Research is being carried out in many areas including the effects of learning Vedic mathematics on children and developing easy and powerful applications of the sutras in geometry, calculus.To find the square of a number that is closer to 10, 100, 1000, use the following principle: The square of 99 is 9801. Subtract the number from its nearest `0' number, 100-99=1 in this case. Then subtract the number obtained with the base number; you get (99-1) 98 in this case. This forms the first two digits of you answer. The last two digits are obtained by the square of difference between the nearest `0' number and the base number; (100-99)to the power of 2=01. How to get the square of a number that is not closer to 10, 100, 1000 etc? The square of 43 is 1849. Add the number to the second digit. 43+3=46 in this case. Multiply the first digit of the number with number obtained in (i); you get 4x46=184. This is the first part of your answer. Square the last digit; 3 to the power of 2=9 in this case. This is the last part of your answer. Therefore, the answer is 1849
