.Adding Time _______________ Here is a nice simple way to add hours and minutes together: Let's add 1 hr and 35 minutes and 3 hr 55 minutes together. What you do is this: make the 1 hr 35 minutes into one number, which will give us 135 and do the same for the other number, 3 hours 55 minutes, giving us 355 Now you want to add these two numbers together: 135 355 ___ 490 So we now have a sub total of 490. What you need to do to this and all sub totals is add the time constant of 40. No matter what the hours and minutes are, just add the 40 time constant to the sub total. 490 + 40 = 530 So we can now see our answer is 5 hrs and 30 minutes!

Multiplication of 99 with any number (You can't use this rule for other numbers) Let me explain this rule by taking examples ____________________________________________ 1. 46*99 = 46*(100-1) = 46*100-46 = 4600-46 = 4554. 2. 362*99 = 362*(100-1) = 36200-362 = 35838. Understand the rule by 1 more example 2841*99 = 2841*(100-1) = 284100-2841 = 281259

4. AravindG

Square of a 2 digit number ending with 5 (You can't use this rule for other numbers) _______________________________________________________________________________ Let me explain this rule by taking examples 35^2 = 3*(3+1) ---25 = 1225 Example. Other example 95^2 = 9*(9+1) ---25 = 9025

5. AravindG

Multiplication of any two numbers, both ranging from 11 to 19. (You can’t use this rule for other numbers) ____________________________________________________________________________________ Let me explain this rule by taking examples 13*19 = (13+9)*10 + (3*9) = 220 + 27 = 247 Means add first number and last digit of the second number take zero in the third place of this number then add product of last digit of the two numbers in it. Example. 18*14 = (18+4)*10 + (8*4) = 220 + 32 = 252

wel thats end of today's tutorial :) hope you all found it useful ! P.S. wish i was better at latexing could have made it more attractive :)

7. nitz

NICE.............!!!!!!!!

8. AravindG

thanks @nitz

9. hba

Have you given multiplication of 11 with any number ?

10. mathmate

@AravindG Nice! Post others soon.

11. AravindG

@hba yep it was there in my previous tutorial

12. AravindG

@mathmate thanks :)

13. mayankdevnani

good job...... @AravindG

14. AravindG

thanks @mayankdevnani

15. mayankdevnani

can you solve it and then clear to me. 29*15=? in 10 sec.

16. mayankdevnani

@AravindG can you???

17. AravindG

(30-1)(30)/2

18. mayankdevnani

plz reply by drawing!!!!

19. AravindG

900-30/2

20. AravindG

|dw:1357742825809:dw|

21. AravindG

:)

22. mayankdevnani

yaaa......another one !!!!!! can i?

23. AravindG

haha u testing me? :P

24. mathmate

I would do 30*15-15=435

25. mayankdevnani

no!!!!!! its a nice .....tutorial for checking it

26. AravindG

thats also a nice method @mathmate

27. mathmate

Bring in more (tests) !!!

28. AravindG

yep @mayankdevnani

29. mayankdevnani

@mathmate how you do this?

30. mayankdevnani

56^2 plz reply by drawing

31. mathmate

No drawing required, it's mental math. 3136=(25+6)*100+6^2

32. mathmate

The 6's comes from (56-50).

33. AravindG

@mathmate nice one :)

34. mathmate

So 59^2=3481

35. mayankdevnani

i don't understand!!!!!!

36. mayankdevnani

|dw:1357743155347:dw|

37. mathmate

Here how this works: We split 56=50+6 So 56^2 = 50^2+2*50*6 + 6^2 = 2500+600 + 6^2 =(25+6)*100+6^ QED

38. mathmate

6^2

39. mayankdevnani

no, by vedic method!!!!

40. AravindG

that calls for me :)

41. mayankdevnani

yaaa

42. mayankdevnani

tring,tring @AravindG olz attend the call

43. mathmate

\( \huge 56^2 = (50+6)^2 = 50^2+2*50*6+6^2 =2500+600+6^2 =(25+6)*100+36 \)

44. mayankdevnani

i know it @mathmate can you solve it? by vedic method @AravindG

45. mathmate

@mayankdevnani do you do Vedic math?

46. AravindG

pls wait i am a bit bsy

47. mayankdevnani

no....

48. mayankdevnani

plz fast @AravindG i have 2 min ....then i have to eat food....

49. mathmate

Intellectual matters trump over food, unless of course you are "requested" to eat food by a superior being.

50. mayankdevnani

thnx....... m waiting for your response.......in advance thank you... @AravindG and @mathmate for your convinient answer

51. AravindG

well in this method we take something called base for computation of square

52. mathmate

Interesting "rencontre". Will meet some other time! Thanks to all! :)

53. mathmate

@Aravindg Keep going!

54. AravindG

for 56^2 we take 50 as base

55. AravindG

ok now what we do is find out deficiency or excess from base .here it is +6

56. mathmate

@AravindG Still there? I am listening. @mayankdevnani will read it later! :)

57. AravindG

srry i am multitasking talking to a friend also ! :P

58. AravindG

ok then ...then we add the excess to the original number that will be 56+6=62

59. AravindG

now multiply this number with the base ,here we took base as 50 so 62*50=2100

60. mathmate

*3100

61. AravindG

oops 3100

62. AravindG

ya now simple add square of deficiency to get final answer! ie 3100+(6)^2=3136 thats all!

63. mathmate

yep! That's great, because it works for all squares. The one I showed only works around 50 (special case that you can add to Vedic math! :P )

64. AravindG

exactly i am planning to explain this topic in detail in next tutorial !! thanks to all those who made this tutorial more interactive and interesting.

65. mathmate

Send me an invitation in your next tutorial! Until now, I don't know anything about Vedic math, but I love mental math! Thanks and talk to you soon! :)

66. AravindG

seeya !

67. mathmate

:)

68. jiteshmeghwal9

|dw:1357799017114:dw|

69. AravindG

3136

70. jiteshmeghwal9

It's also another fast method using identities ;)

71. jiteshmeghwal9

Vedic maths, consisting fastest techniques for calculation, gr8 work @AravindG , keep it up ;)

72. AravindG

thanks! :)

73. jiteshmeghwal9

2500+36+600=3136, right ;)

74. AravindG

hw abt 78^2 ? @jiteshmeghwal9 dont write calculate in mind

75. AravindG

............?

76. jiteshmeghwal9

(80-2)^2=(80)^2+(2)^2-2(80)(2)=?

77. AravindG

did u do that in ur head?

78. jiteshmeghwal9

6400+4-320=6404-320=5084 & no, I only remembered the property :)

79. AravindG

sorry folks gtg ....gn8 !

80. jiteshmeghwal9

Ok ! bye ;)

81. ashlynn143

very informative !!

82. matricked

@mayankdevnani check if it helps u 56^2 square of 6 is 36 and square of 5 is 25 hence square of 56 is (25+6)36=3136 square of 59 is (25+9)81=3481 square of 52 is (25+2)04=2704.... and so on only for nos between 51 -59

83. AravindG

i liked this special case mathmate mentioned :)

84. RyanL.

Wait is this the same math that I see on TV ads?

85. AravindG

86. AravindG

this is vedic maths

87. matricked

there are many more like these silly things i doubt fo Vedic maths

88. RyanL.

Yeah I've seen this on TV. People selling videos and tell you how to do it. They advertise it as a world secret or something lol

89. AravindG

lol i do this for free @RyanL.

90. RyanL.

lol yeah I know it's just funny how it reminded me of that TV ad.

91. matricked

Mathematics should be used to simplify understanding and pacify computation rather than jolting from simpler to a long computing technique

92. mathmate

You can use the same method for 78^2 (excess = 28) 78^2 = (25+excess)*100 + excess^2 = 5300+784=6084 Same as before, but you need to know 28^2=784. Alternatively, you do deficiency of 78 (from 100) = 22 78^2 = (78-deficiency)*100+deficiency^2=(78-22)*100+22^2=5600+484=6084 If you don't memorize/calculate large squares like 22 or 28, you can use the Vedic method: Deficiency from 80 = 80-78=2 78^2=(80-deficiency)*80+deficiency^2=80*76+2^2=6080+4=6084 You can do all of the above in your head.

93. AravindG

:)

94. tamtoan

there's one problem with the method of adding time...for example: 1:00 + 1:00 = 2:00 right? 100 + 100 = 200 and 200+40 = 240 so it's 2:40 ...not 2:00 there should be one more condition under certain circumstance to use your method for adding time.

95. AravindG

@tamtoan thanks for pointing it out ..But I think that case is already understood if one of the time is x:00 and other is y:z we actually do not need any trick at all we already know that the sum =x+y:z .

96. tamtoan

how about , 1:20 + 1:25 = 2:45 but 120+125+40 =285 so what is the time with 285 now ?
