.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

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

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

haha u testing me? :P
mathmate
  • mathmate
I would do 30*15-15=435
mayankdevnani
  • mayankdevnani
no!!!!!! its a nice .....tutorial for checking it

thats also a nice method @mathmate

56^2 plz reply by drawing
mathmate
  • mathmate
No drawing required, it's mental math. 3136=(25+6)*100+6^2
mathmate
  • mathmate
The 6's comes from (56-50).
AravindG
  • AravindG
@mathmate nice one :)
mathmate
  • mathmate
So 59^2=3481

i don't understand!!!!!!

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
mathmate
  • mathmate
6^2
mayankdevnani
  • mayankdevnani
no, by vedic method!!!!
AravindG
  • AravindG
that calls for me :)
mayankdevnani
  • mayankdevnani
yaaa
mayankdevnani
  • mayankdevnani
tring,tring @AravindG olz attend the call
mathmate
  • mathmate
\( \huge 56^2 = (50+6)^2 = 50^2+2*50*6+6^2 =2500+600+6^2 =(25+6)*100+36 \)
mayankdevnani
  • mayankdevnani
i know it @mathmate can you solve it? by vedic method @AravindG
mathmate
  • mathmate
@mayankdevnani do you do Vedic math?
AravindG
  • AravindG
pls wait i am a bit bsy
mayankdevnani
  • mayankdevnani
no....
mayankdevnani
  • mayankdevnani
plz fast @AravindG i have 2 min ....then i have to eat food....
mathmate
  • mathmate
Intellectual matters trump over food, unless of course you are "requested" to eat food by a superior being.
mayankdevnani
  • mayankdevnani
thnx....... m waiting for your response.......in advance thank you... @AravindG and @mathmate for your convinient answer
AravindG
  • AravindG
well in this method we take something called base for computation of square
mathmate
  • mathmate
Interesting "rencontre". Will meet some other time! Thanks to all! :)
mathmate
  • mathmate
@Aravindg Keep going!
AravindG
  • AravindG
for 56^2 we take 50 as base
AravindG
  • AravindG
ok now what we do is find out deficiency or excess from base .here it is +6
mathmate
  • mathmate
@AravindG Still there? I am listening. @mayankdevnani will read it later! :)
AravindG
  • AravindG
srry i am multitasking talking to a friend also ! :P
AravindG
  • AravindG
ok then ...then we add the excess to the original number that will be 56+6=62
AravindG
  • AravindG
now multiply this number with the base ,here we took base as 50 so 62*50=2100
mathmate
  • mathmate
*3100
AravindG
  • AravindG
oops 3100
AravindG
  • AravindG
ya now simple add square of deficiency to get final answer! ie 3100+(6)^2=3136 thats all!
mathmate
  • 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 )
AravindG
  • 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.

@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
AravindG
  • AravindG
i liked this special case mathmate mentioned :)
anonymous

Wait is this the same math that I see on TV ads?
AravindG
  • AravindG
TV ads o.O?
AravindG
  • AravindG
this is vedic maths
anonymous
  • anonymous
there are many more like these silly things i doubt fo Vedic maths
anonymous
  • anonymous
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
AravindG
  • AravindG
lol i do this for free @RyanL.
anonymous
  • anonymous
lol yeah I know it's just funny how it reminded me of that TV ad.

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

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