    1. 1234*11= 13574
    2. 23145*11= 254595
    3. 25431*11= 279741
    4. 51427*11= 565697
    5. 7145235*11= 78597585
    6. 567*11= (add the carry over to the succesive digts only.) 6237
    7. 65873*11= 724603
    8. 9476586*11= 104242446
    9. 326579*11= 3592369
    10. 38*11= 418
    Shucks, took me a bit more than 3 mins! even though the multiplication factor was only 1 - I was slower at additions ... :hide::bonk:bonk. Will try better and practice.



    Wouldn't there be n number of compliments??

    1 and 99
    2 and 98
    3 and 97
    4 and 96
    ..
    ..
    ..
    49 and 51

    Is that the answer?

    GREAT! CORRECT APPROACH! :thumbsup
    so go for table of 99
    99*1= (99 is mutiplier and 1 is multiplicand)
    99*2= (99 is mutiplier and 2 is multiplicand)


    sutra for this table is
    one less of multiplicand/compliment of multiplicand for base 100

    99*1=one less of 1/compliment of 1 for base 100
    =0/99
    99*2=1/98
    99*3=2/97
    99*4=3/96
    .
    .
    .
    99*11=10/89
    ..
    99*15=1485
    99*16=1586

    OBERVATION IS THE KEY NOTE IN VEDIC MATHS.JUST OBSERVE THE NUMBER AND WRITE THE ANS. LEARNIG COMPLIMENTS HELPS IN INCREASING SPEED.

    can we go with table of 98

    Oh! thats nice! Got it..
    Never imagined something this simple cold be done. Just a question, this table could be extended to only 99 * 99 right??

    I am ready for the 98's table. I tried trying to observe the numbers but I couldn't nail a rule (or may be i haven't tried harder) but waiting for it.

    This table can be extanded to 2*3 or 2*4.......digits with slightly different rule

    so for as rule BY OBSERVATION, this rule is very important with it only we can increase our speed.suppose you went for the shopping and you saw a beautiful dress.

    do your mind speaks to you like "what is this ? this is a dress.it is beautiful .and so on....." the ans is "no" you we just pick up the dress and buy it.Rest prossess is just happing in your mind.Same is in case of numbers also
    no need to prounce the process in mind like seven plus eight is equal to fifteen.

    go for this
    1. 2+8
    2. 9-6
    3. 8+7
    4. 4+6
    5. 9*8
    6. 6-3
    7. compliment of 96(for 100)
    8. compliment of 85(for 100)
    9. compliment of 102(for 100)
    10. compliment of 18(for 10)
    remember it should not take more than 10 sec.

    Oh! is it? I will wait for that.

    But yeeeeeeh!! I got the calculations done in 10 seconds (actually 11 sec :} )
    1. 2+8 = 10
    2. 9-6 = 3
    3. 8+7 = 15
    4. 4+6 = 10
    5. 9*8 = 72
    6. 6-3 = 3
    7. compliment of 96(for 100) = 4
    8. compliment of 85(for 100) = 15
    9. compliment of 102(for 100) = 2 (as in minus)
    10. compliment of 18(for 10) = 8 (as in minus)
    (Are the last 2 answers as expected?)

    HI,
    Yesterdy I read your post but could not reply.Actually I was working on square of a number and you know I devloped one interesting and easy pattern .I will write about it later.for todAY I THINK I WANT WORK ON THE NUMBERS ONE BELOW ITS BASE.
    99*1=0/99just to seperate the tables999*8 =7/092 just to seperate the tables9999*86 =859914
    99*2=1/98---------------------999*4 =3/996 ---------------------9999*92 =919908
    99*3=2/97---------------------999*15=14/985 --------------------9999*69 =689931
    99*14=3/86--------------------999*64=63/936 --------------------9999*8 =79992
    99*5= 495--------------------- 999*99=98/901 --------------------9999*- =
    99*56=5544--------------------999*- = ---------------------------9999*- =
    99*87=8613------------------- 999*- = ---------------------------9999*- =
    99*48= 4752------------------ 999*- = ----------------------------9999*- =
    99*99=9801------------------- 999*- = ----------------------------9999*- =
    99*91 =9009------------------ 999*- = ---------------------------- 9999*- =


    ****note the extra zero's in last part.
    For base 100 lart part has 2 digits
    For base 1000 lart part has 3 digits
    For base 10000 lart part has 4 digits

    what so ever work we have done so far let's go for a test of it.
    this time you take the test i will ans.and check my time waiting ..........

    YoUr ans are all correct.This will help us for further caculations.

    hi ram ,

    · 16/32/48/64/80/64/48/32/16
    · as we know tens digits are carry overs so our ans. is

    if u don't mind can u tell me how this ans arrived

    Hi Mahe,:)
    Before repling to the question.please clearify if you know the method of finding square of a number by duplex method of vedic maths.
    Your reply to this post will help me to make the ans. interesting for you.

    hi ram,

    ya, i know how found a square by duplex method,but

    ) 44444^2=
    · count the 4's
    · it comes for 5 times in the numbers
    · so now in ans. write down square of 4 that is 16 as the last part of the ans.
    · than go on writing table of 16 for 5 times (duplex of the numbers will give us the table of 16)
    · than reverse of the table of 16 up to 1
    · 16/32/48/64/80/64/48/32/16

    i can't u/s how arrive this ans.

    as we know tens digits are carry overs so our ans. is

    Hi Ram ,

    Wonderful examples.

    I could understand 44444^2.

    But could not get 66666^2. And also could not get something like 8888^2. Could you please elaborate on these.

    -krk
