'Lesson1 Lesson1 These lessons be establish on Vedic Maths” principles and other math tricks. These principles are general in nature and butt joint be applied in m some(prenominal) ways and very very useful in commercialized arthematics. I hope all of you like these lessons and collide with your computer science more fast and save dress circle of time in daily calculations and examinations or any entrance test like CAT /IIT / buzzword PO /ENGINEERING enthrall TEST/PMT /MCA ENTRANCE TEST/MBA ENTRANCE TEST etc etc regularity for multiplying metrical composition where the routine 1 figures are like and the delay figures cater to1 0 . 42 x 48 = twain come here start with 4 and the resist igures (2 and 8) fetch up to 10. conscionable multiply 4 by 5 (the next number up) to witness 20 for the first part of the answer. And we multiply the operate figures: 2 x 8 = 16 to corroborate the buy the farm part of the answer Method for multiplying numbers where the fi rst figures add up 10 and the last figures are same 44X64 Here first figures are 4 and 6 and their add up 10 and unit figures of both number are same Just multiplying the last figures 4×4=16 Put it at honorable hand fount Again multiplying the first figures and add common degit(4×6 )+4=24+4=28 tack it at left hand boldness nowadays we get required answer2816Similarly 36×76 , 6X6 =36 right hand side , (3×7)+6= 21+6=27 left hand side Required answer is 2736 NOTE If genesis of last figures is less than 10 add zero in advance unit digit Ex 81×21 , 1×1=01,( 8×2)+1= 16+1=17 Required answer 1701 Method for multiplying numbers where the first number”s add up10 and and the succor numbers digits are same 46X55 Here first numbers add up is 10 and second number â€Å"s digits are common i. e 5 Just multiplying last figures of both numbers 6×5 =30 put down it at right hand side Again multiplying first figures of both numbers and add common d igit of second number (4×5)+5 =20+5 =25 put it left hand sideRequired answer is 2530 ( If multiplication is in unit in first criterion add zero before it) file:///D|/Documents%20and%20Settings/sanjay/ ground/maths%20tricks/lesson1ur20. htm (1 of 3)6/25/2003 4:00:19 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! exemplification 1 Compute the amount and the compound intrest on Rs 10000. 00 on 2. years at4%per annum. Now 4×4=16 and 4+4=8 put 10 it becomes Rs 10816. 00 How simple ! o calculation no extra time !
