JUST BEING TRICKY.........


  • If you want to find the square of 45, you can employ the Ekadhikena Purvena sutra ("By one more than the one before"). The rule says since the first digit is 4 and the second one is 5, you will first have to multiply 4 (4 +1), that is 4 X 5, which is equal to 20 and then multiply 5 with 5, which is 25. The answer is 2025. Now, you can employ this method to multiply all numbers ending with 5.
  • If you want to subtract 4679 from 10000, you can easily apply the Nikhilam Navatashcaramam Dashatah sutra ("All from 9 and the last from 10"). Each figure in 4679 is subtracted from 9 and the last figure is subtracted from 10, yielding 5321. Similarly, other sutras lay down such simple rules of calculation.


  • Take a number ending with 5 , for example, 25..
    Can you tell it's square number?
    I can very easily, it is 625...
     Do you know how?
    Let's see:
    25 square- 5 squared is 25, so we can assure that the last two digits are 2 and 5
    now, multiply the number with it's successor, so, successor of 2 is 3..
    so, thus 2*3 gives us 6..
    so, the number obtained is 625 ( just try out! and don't forget to check your answer)...
    You can use this way for any number that ends with 5.
    These are the precious tricks of vedic maths..
    So, don't you see the level of progression at even that early period?
    India really laid the base of the present-day mathematics.
    Be proud to say that you are an Indian....


    HOW TO MULTIPLY TO TWO DIGIT NUMBER FASTER
                                                                  Rahul Rajendran XB
     FIRST METHOD
    1.                     13 x 12 =?
    Ans : step one :  FIRST ADD 2 [LAST DIGIT OF SECOND NUMBER ] TO 3 [LAST          
                                                             Digit of first number]. Resullt = 15.
                     Step twoMULTIPLY LAST DIGITORF FIRST NO: WITH THAT                                   
                                        OF SECOND NO: AND PLACE IT WITH FIRST RESULT 15.
                                              RESULT: [3X2 = 6] , 156 .
                                             YOUR ANSER IS 156.
    SECOND METHOD
    1.  19 X 14
    STEP ONE : 14 = 10 +4 . FIRST MULTIPLY 19  
                           WITH 10. RESULT = 190.
    STEP TWO : THEN WITH 4. RESULT = 76.
    STEP THREE : NOW ADD 190 WITH 76.
    YOUR ANSWER IS 266
