from Ekeeda Hello friends today we are going to see what is one compliment
method so in today’s video we are going to see how the binary subtraction is
performed using the ones complement method what is compliment method is
nothing but in this method you can perform the subtraction by using the
binary addition method so there are different kind of rules and there are
different kind of set of steps using which you can perform the ones
compliment subtraction so let’s start with the words compliment subtraction so we have so far we have seen the
binary addition and the subtraction rule now we are going to see what they mean
by the ones complement subsection method so I am going to tell you the different
steps to perform the subtraction the step number one is to find out the
binary of number a suppose you have the two number that is number a and the
number P the first step will always be to find out the binary of number a okay
now we have to number that is a and B so in this case my first number will be a
and my second number will be let us take an example the value of a each step and
the value of B is 15 so first number will be 10 and the second number will be
15 so that in the first step you will find out the binary of 10
okay now let’s now let’s see the next step in the second step find out the
ones complement of P in our case the second number is 15 so what we will do
is we will find out the ones complement of 50 so this is me so in the second
step we will find out the ones complement of P now let’s see the third
step in the third step what we have to do is we have to add the safe number one
and step number two but in the first step what we have caught the binding
your fail that means you will add the binary of number a and in the second
step you have got one’s complement of B that is one’s complement of 50 so in the
second step once come here 15 so the binary of a and the ones complement of
50 you will add in the step number three okay
now this step for the step four plays a very important role because from the
step four you will be able to know whether your answer is positive or
negative so in the binary how you will identify whether your answer is positive
or negative so there is one trick over here now watch carefully we have two
numbers means we have assumed a an example two numbers that is number 10
and number 15 okay so in a normal deck see my subtraction if you subtracted
number 10 from 15 what you will get you will get the minus five okay so in the
decimal you are able to know how to give the minus sign that is when we are
subtracting the small number very exciting when we are subtracting the big
number from this morning so here also we have country using which we can identify
when there are binary subtraction is positive or negative so from the step
number three you will get the answer that is of addition of step number four
nine two okay I mean step number four in step number four what we are going to do
is if carry one is present like suppose you have four digits of binary like this
one zero one zero okay after step number three you have got this as an answer and
after addition of tune and suppose this this one carries freeze him okay this
this is the extra one okay if the caddiebuddy is present then what
you have to do is then you are answer is positive okay
now using this trick you can identify whether your answer is positive or
negative so if after the addition after the step three if you got the Cadi
that means young city squad city okay and if the cabbies up same that means
you answer this thing you do suppose this one is not present over here so
that means your answer is negative but how to write it in its final correct
answer this one this step won’t give you the final correct answer okay we have to
find out to find the correct answer this step only gives us the information
you have to make the end or uncaring and if you answer is negative that means if
the carry is of same you have to find out the ones complement that particular
value that you got from second of a three now what do you mean by the end
around cattle in end are carrying what you do if the carry is present you
simply add this in this answer so what you will get 0
plus 1 is 1 1 as it is 0 as too simple so this will be of 5 minutes
this is just an example this is not the subtraction of 10 and 15 I have just
taken the example under this values okay so if you got the callee as 1 that means
making the interim carry and end-around carry means adding 1 into that ok now
what is the carry is absent suppose this carry is not present here we have only
got 1 0 1 0 fellow then I answer is negative but this is not the final
corrected answer for this again we have to find out the ones complement of that
answer once suppose we have got 1 0 1 0 in the step number 3 and the carry is
absent that means I answer is negative and we have to find out the ones
complement of number 1 what do you mean by the ones compliment once compliment
is simply the blessing 0 by fans and replacing 1 by zeros so that means if 0
is present we will replace the 0 by a fan and if the one is present we will
declare this week 1 by 0 now again 0 is present now find out the
ones from diamond what we will do is we will replace this 0 value by a fan and
again if money’s present we will replace this value by 0 okay so this is the
important step if you write down the answer in a set number three only thank
positive or negative and then only you can verify it
to verify the answer what you can do is first of all just perform the addition
or subtraction in a decimal and after if you are getting the answer convert this
final answer binary number again into the dressing so that you will be able to
now let us take an example of 9 minus 5 over here okay here what we have to do
is we have to perform the binary subtraction and we will pop on the
binary subtraction using one’s complement method so let’s start the
strength and say ok first it what was the first step first step was
to find out the binary of a okay here we have two
numbers so assume this number as E and this number asking okay so according to
the first step we have to find out the binary of it but so what is the binary
of nine the binary of many means this is the binary of nine okay damn say I said
in the second step we have to find out the ones complement of B so here are our
second number is five so to find out the ones complement of five first of all we
have to convert this decimal number into the binary so what is the binary
conversion on file so the conversion of five is zero one
zero one okay and what we have to do is in the second but see we have seen that
we have to and the step number one and step number two but in the set number
two if you have to find out the ones complement of B that is the second
number so here we have just find out the binary conversion of five now to find
out the ones complement of five we will just replace 1 by 3 0 and 0 by 1 so this
is the ones complement now let’s start with the last X in this stage is very
important in this stage we have to add the second number one and two so in a
set number 1 we have seen 1 0 0 and from the step number two we are positive ones
complement of 5 now let’s do the addition 1 plus 0 can
give us 1 so you dope less what will give once 1 0 / 0 being over 0 and in
the binary addition we have seen that 1 plus 1 will always give us 0 and carry
baby 1 so how you will identify whether the
Kyrie is present or not here we have the fortitude and here also we have the
fortitude but after answer we have got five digit okay so if one is present
that means the carry is present now in the step number four we have seen if the
carry is present if the carry is present we have to make the end round carry and
a around carry means we have to add this scary in the answer so what we will do
is we will make the end around carry okay so we will add this one in do not
these answers 1 plus 1 will give 0 carry will be 1 and again 1 plus 1 will give
us 0 carry will be fun and this 0 plus 1 1 & 0
now let’s see so now this is our final answer but to verify this answer let’s
see 9 minus 5 in decimal will give us 4 ok and what we will do to verify this
answer we will convert this mind enough oil to a decimal number so let’s convert
this number so 1 is to 4 these are the advantages so from the vantage as you
can see we are called this answer as 4 therefore in the final subtraction we
have this value is zero one zero zero
Thank You France for watching today’s video today we have seen how do we
perform the ones of payment method also different kind of method to perform
subtraction we are going to see in the next video so stay tuned to equalize
