number fetish human calculator I hold four World Records and 15 Limca records
four World Records and 15 Limca records
four World Records and 15 Limca records for being one of the fastest
for being one of the fastest
for being one of the fastest mathematicians in the world before I go
mathematicians in the world before I go
mathematicians in the world before I go ahead and talk about my story and about
ahead and talk about my story and about
ahead and talk about my story and about my journey with mental mathematics and
my journey with mental mathematics and
my journey with mental mathematics and about how I explored my true potentials
about how I explored my true potentials
about how I explored my true potentials I would like to begin my talk by doing
I would like to begin my talk by doing
I would like to begin my talk by doing some of those mathematical stunts so
some of those mathematical stunts so
some of those mathematical stunts so anyone in the audience would like to
anyone in the audience would like to
anyone in the audience would like to volunteer a couple of them well yeah
volunteer a couple of them well yeah
volunteer a couple of them well yeah come on we’ll come up onto the stage and
come on we’ll come up onto the stage and
come on we’ll come up onto the stage and one more someone from there yeah come
one more someone from there yeah come
one more someone from there yeah come down open the cattle bring your phones
down open the cattle bring your phones
down open the cattle bring your phones with you open the calculator application
with you open the calculator application
with you open the calculator application on your phone so that when I do this
on your phone so that when I do this
on your phone so that when I do this come up onto the stage so why I do this
come up onto the stage so why I do this
come up onto the stage so why I do this you’ll have a check of it covering ready
you’ll have a check of it covering ready
you’ll have a check of it covering ready so since I don’t know what applications
so since I don’t know what applications
so since I don’t know what applications these people are using I’d like to make
these people are using I’d like to make
these people are using I’d like to make sure that their calculators are working
sure that their calculators are working
sure that their calculators are working fine so that can someone give me a two
fine so that can someone give me a two
fine so that can someone give me a two digit number from their 52 can you give
digit number from their 52 can you give
digit number from their 52 can you give another two-digit number okay multiply
another two-digit number okay multiply
another two-digit number okay multiply them together
them together
them together is it one one four four if it is then
is it one one four four if it is then
is it one one four four if it is then you’re fine like you’re in the lake yeah
you’re fine like you’re in the lake yeah
you’re fine like you’re in the lake yeah cool
cool
cool so since I know that these people are
so since I know that these people are
so since I know that these people are using the proper applications let us
using the proper applications let us
using the proper applications let us begin with my first demonstration which
begin with my first demonstration which
begin with my first demonstration which would be called the back in fourth
would be called the back in fourth
would be called the back in fourth edition so well more what’s the most
edition so well more what’s the most
edition so well more what’s the most enthusiastic row here anyone okay
enthusiastic row here anyone okay
enthusiastic row here anyone okay yeah okay the last one obviously so I
yeah okay the last one obviously so I
yeah okay the last one obviously so I want to each of you from that row to
want to each of you from that row to
want to each of you from that row to call out a two-digit number
call out a two-digit number
call out a two-digit number all right each of you to call out the
all right each of you to call out the
all right each of you to call out the two-digit number I’ll say plus and the
two-digit number I’ll say plus and the
two-digit number I’ll say plus and the next one calls out a two-digit number
next one calls out a two-digit number
next one calls out a two-digit number again and we’ll go till the very end so
again and we’ll go till the very end so
again and we’ll go till the very end so begin 82 so you’ll have to add all of
begin 82 so you’ll have to add all of

I’m sure somewhere okay so let me make
I’m sure somewhere okay so let me make this clear because there was some human
this clear because there was some human
this clear because there was some human error here so let’s cut the human error
error here so let’s cut the human error
error here so let’s cut the human error the second thing which I’m gonna do okay
the second thing which I’m gonna do okay
the second thing which I’m gonna do okay go back
go back
go back ha it’s called the flash number

okay no no no not yet ah so how did a
okay no no no not yet ah so how did a regular school going kid like me do this
regular school going kid like me do this
regular school going kid like me do this become the fastest human calculator in
become the fastest human calculator in
become the fastest human calculator in the world my story starts goes back to
the world my story starts goes back to
the world my story starts goes back to 2005 that was when I was 6 year old I
2005 that was when I was 6 year old I
2005 that was when I was 6 year old I was good in mathematics
was good in mathematics
was good in mathematics I was I was good I was good in doing
I was I was good I was good in doing
I was I was good I was good in doing calculations and all but it was not
calculations and all but it was not
calculations and all but it was not anything quite evident and it was on one
anything quite evident and it was on one
anything quite evident and it was on one festival evening on Raksha Bandhan that
festival evening on Raksha Bandhan that
festival evening on Raksha Bandhan that I met with the road accident
I met with the road accident
I met with the road accident it was a severe injury I suffered a
it was a severe injury I suffered a
it was a severe injury I suffered a severe skull bone fracture followed by a
severe skull bone fracture followed by a
severe skull bone fracture followed by a 90 stitches around my head and I was in
90 stitches around my head and I was in
90 stitches around my head and I was in a coma kind of thing for a week or so
a coma kind of thing for a week or so
a coma kind of thing for a week or so and then I was bedridden for a year so
and then I was bedridden for a year so
and then I was bedridden for a year so that was the time initially the first
that was the time initially the first
that was the time initially the first three months I don’t even remember what
three months I don’t even remember what
three months I don’t even remember what happened like that was three months
happened like that was three months
happened like that was three months taken away from my life so what all I
taken away from my life so what all I
taken away from my life so what all I used to remember there was to wake up at
used to remember there was to wake up at
used to remember there was to wake up at my mom’s face and then probably slim
my mom’s face and then probably slim
my mom’s face and then probably slim again so after three months or four
again so after three months or four
again so after three months or four months I was kind of I don’t know
months I was kind of I don’t know
months I was kind of I don’t know recovering and that’s when I was at home
recovering and that’s when I was at home
recovering and that’s when I was at home I didn’t have anything to do as cut off
I didn’t have anything to do as cut off
I didn’t have anything to do as cut off from the world and then there were some
from the world and then there were some
from the world and then there were some puzzle books which were gifted by my dad
puzzle books which were gifted by my dad
puzzle books which were gifted by my dad probably because he wanted to me keep me
probably because he wanted to me keep me
probably because he wanted to me keep me occupied didn’t want me to probably I
occupied didn’t want me to probably I
occupied didn’t want me to probably I don’t know be lazy all the time or be
don’t know be lazy all the time or be
don’t know be lazy all the time or be sleeping because that would really
sleeping because that would really
sleeping because that would really reduce the thing incapacities and all so
reduce the thing incapacities and all so
reduce the thing incapacities and all so I started doing the puzzle books and
I started doing the puzzle books and
I started doing the puzzle books and what interested me the most was doing
what interested me the most was doing
what interested me the most was doing calculations there is no picture of a
calculations there is no picture of a
calculations there is no picture of a sheep herd in my room so that I could
sheep herd in my room so that I could
sheep herd in my room so that I could count them and sleep so I used to count
count them and sleep so I used to count
count them and sleep so I used to count tables in my head and fall asleep and
tables in my head and fall asleep and
tables in my head and fall asleep and two years from there I won my first
two years from there I won my first
two years from there I won my first regional championship in speed
regional championship in speed
regional championship in speed mathematics and seven years from there I
mathematics and seven years from there I
mathematics and seven years from there I don’t know I don’t know Here I am so
don’t know I don’t know Here I am so
don’t know I don’t know Here I am so yeah thank you from there they’re on
yeah thank you from there they’re on
yeah thank you from there they’re on after all that I have been doing since
after all that I have been doing since
after all that I have been doing since then I my journey in this field taught
then I my journey in this field taught
then I my journey in this field taught me a few things mentioned mathematics
me a few things mentioned mathematics
me a few things mentioned mathematics doing minor in mathematics doing
doing minor in mathematics doing
doing minor in mathematics doing calculations didn’t develop me in just
calculations didn’t develop me in just
calculations didn’t develop me in just doing it quickly it wasn’t just teaching
doing it quickly it wasn’t just teaching
doing it quickly it wasn’t just teaching me mathematics it was teaching me
me mathematics it was teaching me
me mathematics it was teaching me something more so I wondered what was
something more so I wondered what was
something more so I wondered what was happening because through my practice
happening because through my practice
happening because through my practice over the span of three four years what I
over the span of three four years what I
over the span of three four years what I really did observe that my memories give
really did observe that my memories give
really did observe that my memories give my memory the way I was grasping things
my memory the way I was grasping things
my memory the way I was grasping things the way I was looking at things the way
the way I was looking at things the way
the way I was looking at things the way I was analyzing things and then the
I was analyzing things and then the
I was analyzing things and then the decision making all of these improved
decision making all of these improved
decision making all of these improved and that was because of my training in
and that was because of my training in
and that was because of my training in mental mathematics so it developed me as
mental mathematics so it developed me as
mental mathematics so it developed me as a person overall it’s just not just
a person overall it’s just not just
a person overall it’s just not just mathematics in which it did and from
mathematics in which it did and from
mathematics in which it did and from there there the I was a human calculator
there there the I was a human calculator
there there the I was a human calculator by then I got some Fame and I was doing
by then I got some Fame and I was doing
by then I got some Fame and I was doing things I broke a couple of Records but
things I broke a couple of Records but
things I broke a couple of Records but then that wasn’t enough for me I was
then that wasn’t enough for me I was
then that wasn’t enough for me I was racing past other people right I was
racing past other people right I was
racing past other people right I was raising first other people but then even
raising first other people but then even
raising first other people but then even then that was still human that was not
then that was still human that was not
then that was still human that was not something extraordinary so in 2015 that
something extraordinary so in 2015 that
something extraordinary so in 2015 that is two years ago I took up a challenge
is two years ago I took up a challenge
is two years ago I took up a challenge to prove the world that our brains are
to prove the world that our brains are
to prove the world that our brains are capable of doing things that are really
capable of doing things that are really
capable of doing things that are really really what we think are impossible by
really what we think are impossible by
really what we think are impossible by racing against a calculator so that was
racing against a calculator so that was
racing against a calculator so that was a record attempt where there was a
a record attempt where there was a
a record attempt where there was a person on a calculator and he was doing
person on a calculator and he was doing
person on a calculator and he was doing calculations there and I was doing the
calculations there and I was doing the
calculations there and I was doing the calculations here and I would be
calculations here and I would be
calculations here and I would be reciting out the intermediate results
reciting out the intermediate results
reciting out the intermediate results and he’d be doing the same and after a
and he’d be doing the same and after a
and he’d be doing the same and after a certain time we’d be comparing ourselves
certain time we’d be comparing ourselves
certain time we’d be comparing ourselves and then we found out that I was quicker
and then we found out that I was quicker
and then we found out that I was quicker than the guy on the calculator the whole
than the guy on the calculator the whole
than the guy on the calculator the whole the whole point of me doing this record
the whole point of me doing this record
the whole point of me doing this record was not to get the recorder it was to
was not to get the recorder it was to
was not to get the recorder it was to prove the world that we as people should
prove the world that we as people should
prove the world that we as people should believe that be you’re way ahead of all
believe that be you’re way ahead of all
believe that be you’re way ahead of all the machines which have been fatal now
the machines which have been fatal now
the machines which have been fatal now so I’m gonna do that right now I’m gonna
so I’m gonna do that right now I’m gonna
so I’m gonna do that right now I’m gonna show you guys that I’m gonna race
show you guys that I’m gonna race
show you guys that I’m gonna race against a calculator here so that was
against a calculator here so that was
against a calculator here so that was called the mental speed barrier before
called the mental speed barrier before
called the mental speed barrier before that no one could race against a
that no one could race against a
that no one could race against a calculator which proved to be false so
calculator which proved to be false so
calculator which proved to be false so someone now
someone now
someone now any other one Indian would like to come
any other one Indian would like to come
any other one Indian would like to come up with a calculator here cool come down
up with a calculator here cool come down
up with a calculator here cool come down Oh my calculator application again so Oh
Oh my calculator application again so Oh
Oh my calculator application again so Oh careful man
okay so the thing is we are gonna take a
okay so the thing is we are gonna take a two digit number all right
two digit number all right
two digit number all right and I’m gonna add it to itself say if
and I’m gonna add it to itself say if
and I’m gonna add it to itself say if it’s 78 I’m going to do 78 156 234 and
it’s 78 I’m going to do 78 156 234 and
it’s 78 I’m going to do 78 156 234 and I’ll be going on this is different from
I’ll be going on this is different from
I’ll be going on this is different from my other demonstrations because you’ll
my other demonstrations because you’ll
my other demonstrations because you’ll exactly know what’s going on in my head
exactly know what’s going on in my head
exactly know what’s going on in my head don’t freak out so you’ll have to do
don’t freak out so you’ll have to do
don’t freak out so you’ll have to do that you’ll have to keep adding the
that you’ll have to keep adding the
that you’ll have to keep adding the number to itself if it’s 38 you need to
number to itself if it’s 38 you need to
number to itself if it’s 38 you need to put 38 plus 38 plus 38 and after some
put 38 plus 38 plus 38 and after some
put 38 plus 38 plus 38 and after some time we are gonna compare ourselves okay
time we are gonna compare ourselves okay
time we are gonna compare ourselves okay cool don’t do it wrongly because huh so
cool don’t do it wrongly because huh so
cool don’t do it wrongly because huh so who’s gonna select that two-digit number
who’s gonna select that two-digit number
who’s gonna select that two-digit number anyone okay all right 97 let’s don’t
anyone okay all right 97 let’s don’t
anyone okay all right 97 let’s don’t begin yet three two one go 97 184 291
begin yet three two one go 97 184 291
begin yet three two one go 97 184 291 388 485 582 676 873 9 7106 nine one one

six four two six one one three five zero
six four two six one one three five zero one four five five do it man one five
one four five five do it man one five
one four five five do it man one five two one any clothes Oh No
so thanks thanks a lot so I’d like to
so thanks thanks a lot so I’d like to end my talk telling one thing that our
end my talk telling one thing that our
end my talk telling one thing that our brains are capable of doing things that
brains are capable of doing things that
brains are capable of doing things that we can’t even imagine off it’s about
we can’t even imagine off it’s about
we can’t even imagine off it’s about time we started exploring our true
time we started exploring our true
time we started exploring our true potentials thank you Bhanu Prakash
