afternoon ladies and gentlemen to begin with I would like to ask you guys a

with I would like to ask you guys a

with I would like to ask you guys a question what is one plus one show me

question what is one plus one show me

question what is one plus one show me the answer was intense well the answers

the answer was intense well the answers

the answer was intense well the answers do obviously but that only works in some

do obviously but that only works in some

do obviously but that only works in some circumstances you may think that I’m

circumstances you may think that I’m

circumstances you may think that I’m being strange but soon you won’t I will

being strange but soon you won’t I will

being strange but soon you won’t I will give evidence examples showing that

give evidence examples showing that

give evidence examples showing that things are going wrong in this role now

things are going wrong in this role now

things are going wrong in this role now let’s get back and think about the

let’s get back and think about the

let’s get back and think about the question again

question again

question again why is to not always the right answer

why is to not always the right answer

why is to not always the right answer look a husband and wife are two people

look a husband and wife are two people

look a husband and wife are two people and they can make a family with the

and they can make a family with the

and they can make a family with the children and then two through mitosis a

children and then two through mitosis a

children and then two through mitosis a cell plus another cell can make four

cell plus another cell can make four

cell plus another cell can make four cells mixing two color together which is

cells mixing two color together which is

cells mixing two color together which is one plus one can create one new color so

one plus one can create one new color so

one plus one can create one new color so the reality is that one plus one is not

the reality is that one plus one is not

the reality is that one plus one is not always certain yet according to the

always certain yet according to the

always certain yet according to the definition of math is this system AG

definition of math is this system AG

definition of math is this system AG treatment between magnitude relationship

treatment between magnitude relationship

treatment between magnitude relationship our relationship between quantities

our relationship between quantities

our relationship between quantities expressed symbolically so it’s a

expressed symbolically so it’s a

expressed symbolically so it’s a systemic stuff and it shall never be

systemic stuff and it shall never be

systemic stuff and it shall never be uncertain and plus speaking of math was

uncertain and plus speaking of math was

uncertain and plus speaking of math was even the use of it well your teacher may

even the use of it well your teacher may

even the use of it well your teacher may say that you will have to do

say that you will have to do

say that you will have to do calculations whenever grow up but but

calculations whenever grow up but but

calculations whenever grow up but but who on earth doesn’t carry a calculator

who on earth doesn’t carry a calculator

who on earth doesn’t carry a calculator with him all the time you all have on

with him all the time you all have on

with him all the time you all have on your phone right there’s calculator

your phone right there’s calculator

your phone right there’s calculator taking over for there much faster than

taking over for there much faster than

taking over for there much faster than brain and if I ask you guys to give me

brain and if I ask you guys to give me

brain and if I ask you guys to give me the answer of let’s say 126 times 22 and

the answer of let’s say 126 times 22 and

the answer of let’s say 126 times 22 and 5 seconds

5 seconds

5 seconds no one won’t be able to do it Oh

no one won’t be able to do it Oh

no one won’t be able to do it Oh literally no one so if there’s a

literally no one so if there’s a

literally no one so if there’s a superior stuff why don’t we use them now

superior stuff why don’t we use them now

superior stuff why don’t we use them now one plus one this is a really a daydream

one plus one this is a really a daydream

one plus one this is a really a daydream to actual human practice and not only is

to actual human practice and not only is

to actual human practice and not only is this mathematics theory being nonsense

this mathematics theory being nonsense

this mathematics theory being nonsense in real life there are many more

in real life there are many more

in real life there are many more confusing stuff in the thing

confusing stuff in the thing

confusing stuff in the thing just ticket mix number that’s they’re

just ticket mix number that’s they’re

just ticket mix number that’s they’re known as a non fraction number but they

known as a non fraction number but they

known as a non fraction number but they really shouldn’t be excluded from the

really shouldn’t be excluded from the

really shouldn’t be excluded from the fraction family although they are come

fraction family although they are come

fraction family although they are come mixed number

mixed number

mixed number they still contains a fraction within

they still contains a fraction within

they still contains a fraction within them so it’s a mixture of a fraction and

them so it’s a mixture of a fraction and

them so it’s a mixture of a fraction and the whole number you can’t say a cloth

the whole number you can’t say a cloth

the whole number you can’t say a cloth with 50% of warm that has no wool when

with 50% of warm that has no wool when

with 50% of warm that has no wool when there is physically 50% of them in there

there is physically 50% of them in there

there is physically 50% of them in there and so do the mixed number

and so do the mixed number

and so do the mixed number there is a fraction a curing literally

there is a fraction a curing literally

there is a fraction a curing literally in their existence and so it’s

in their existence and so it’s

in their existence and so it’s absolutely a form of fraction a fraction

absolutely a form of fraction a fraction

absolutely a form of fraction a fraction and also they’re equivalent to the

and also they’re equivalent to the

and also they’re equivalent to the improper fraction

improper fraction

improper fraction if the improper fraction in snow has a

if the improper fraction in snow has a

if the improper fraction in snow has a kind of fraction but the mixed number

kind of fraction but the mixed number

kind of fraction but the mixed number isn’t a mixed number is just a

isn’t a mixed number is just a

isn’t a mixed number is just a simplified form of the improper and so

simplified form of the improper and so

simplified form of the improper and so one is equal with another for example 3

one is equal with another for example 3

one is equal with another for example 3 and 4/7 is equal to twenty five sevenths

and 4/7 is equal to twenty five sevenths

and 4/7 is equal to twenty five sevenths they both mean 25 divided by seven just

they both mean 25 divided by seven just

they both mean 25 divided by seven just expressed in a different way and if you

expressed in a different way and if you

expressed in a different way and if you can’t do the math the result of 25

can’t do the math the result of 25

can’t do the math the result of 25 divided by seven will be the same as 3

divided by seven will be the same as 3

divided by seven will be the same as 3 times 7 plus 4/7 so they are equivalent

times 7 plus 4/7 so they are equivalent

times 7 plus 4/7 so they are equivalent and since the definition of equal is the

and since the definition of equal is the

and since the definition of equal is the same as they shouldn’t be in different

same as they shouldn’t be in different

same as they shouldn’t be in different categories because they are the same so

categories because they are the same so

categories because they are the same so they’ve got the same identity and both

they’ve got the same identity and both

they’ve got the same identity and both sits into the category of fraction so as

sits into the category of fraction so as

sits into the category of fraction so as long as improper fractions is included

long as improper fractions is included

long as improper fractions is included in the fraction category mixed numbers

in the fraction category mixed numbers

in the fraction category mixed numbers shouldn’t be excluded so let me ask you

shouldn’t be excluded so let me ask you

shouldn’t be excluded so let me ask you again what’s one plus one and it’s mixed

again what’s one plus one and it’s mixed

again what’s one plus one and it’s mixed number a kind of fraction I want to

number a kind of fraction I want to

number a kind of fraction I want to spread my theory because I believe that

spread my theory because I believe that

spread my theory because I believe that math is the system of strict rules but

math is the system of strict rules but

math is the system of strict rules but no rule should ever exist without us at

no rule should ever exist without us at

no rule should ever exist without us at least taking a critical look at it Oh

least taking a critical look at it Oh

least taking a critical look at it Oh some rule should be bent some good ones

some rule should be bent some good ones

some rule should be bent some good ones can we follow and some can even be

can we follow and some can even be

can we follow and some can even be broken but you’ve been the best rule on

broken but you’ve been the best rule on

broken but you’ve been the best rule on earth such as those we find in

earth such as those we find in

earth such as those we find in mathematic

mathematic she’ll always be questioned thanks man

she’ll always be questioned thanks man

she’ll always be questioned thanks man before we decided whether to follow them
