Lesson1 Lesson1 These lessons are based on Vedic Maths principles and other math tricks. These principles are public in nature and can be applied in many ways and genuinely very useful in commercial arthematics. I hope all of you like these lessons and make your calculation more fast and save lot of time in daily calculations and examinations or any entrance discharge like CAT /IIT /BANK PO /ENGINEERING enthral TEST/PMT /MCA ENTRANCE TEST/MBA ENTRANCE TEST etc etc Method for multiplying numbers where the premier figures are uniform and the closing curtain figures add to1 0 . 42 x 48 = Both numbers here start with 4 and the last igures (2 and 8) add up to 10. just multiply 4 by 5 (the next number up) to get 20 for the start startle of the answer. And we multiply the last figures 2 x 8 = 16 to get the last part of the answer Method for multiplying numbers where the first figures add up 10 and the last figures are same 44X64 Here first figures are 4 and 6 and their add up 10 and social unit figures of both number are same Just multiplying the last figures 44=16 Put it at right hand nerve Again multiplying the first figures and add common degit(46 )+4=24+4=28 put it at left hand side Now we get necessitate answer2816Similarly 3676 , 6X6 =36 right hand side , (37)+6= 21+6=27 left hand side Required answer is 2736 NOTE If multiplication of last figures is less than 10 add zero before unit digit Ex 8121 , 11=01,( 82)+1= 16+1=17 Required answer 1701 Method for multiplying numbers where the first numbers add up10 and and the second numbers digits are same 46X55 Here first numbers add up is 10 and second number s digits are common i. e 5 Just multiplying last figures of both numbers 65 =30 put it at right hand side Again multiplying first figures of both numbers and add common digit of second number (45)+5 =20+5 =25 put it left hand sideRequired answer is 2530 ( If multiplication is in unit in first step add zero before it) file///D/Documents%20and%20Settin gs/sanjay/Desktop/maths%20tricks/lesson1ur20. htm (1 of 3)6/25/2003 40019 PM Lesson1 Multiplying numbers just over 100. 108 x 109 = 11772 The answer is in two parts 117 and 72, 117 is just 108 + 9 (or 109 + 8), and 72 is just 8 x 9. Similarly 107 x 106 = 11342 HOW USEFUL IS THIS CALCULATION EXAMPLE 1 Compute the amount and the compound intrest on Rs 10000. 00 on 2. eld at4%per annum. Now 44=16 and 4+4=8 put 10 it becomes Rs 10816. 00 How plain o calculation no extra time Practice Test 1 Solve mentally these questions Note down your calculation time by watch (Suggested time 90 seconds) 22 X 28 35 X 35 48 X 42 73 X 33 12 X 92 48 X 28 28 X 22 37 X 88 91 X 66 118 X105 109 X108 112 X106 91 X 99 33 X 37 55X55 Now check your answer with the help of a calculator Back Home close file///D/Documents%20and%20Settings/sanjay/Desktop/maths%20tricks/lesson1ur20. htm (2 of 3)6/25/2003 40019 PM Lesson1 file///D/Documents%20and%20Settings/sanjay/Desktop/maths%20tricks/lesson1ur20. htm (3 of 3)6/ 25/2003 40019 PM
