Hello and welcome.
This lecture is based on the addition method.
Based on we know this is also called L'Ermitage or Left-to-right method of addition.
Spark means no time with any spark of flame or in other words, we can see that in no time we can write
dances in this technique.
We need two concepts and no concept and getting or not getting no concept.
Let's try to understand the concept of a number when we are two numbers supporting it and we get the
same as 12.
Then last digit of the is called a number.
This is also called Unity Dumble or once.
But for this technique, we are going to call this last digit of those some as a number.
For example, six plus seven is 13 here.
Three.
Is that a number?
If the sum is one digit number.
See, if we add eight and one, we get guns is nine and it is a page number, then this nine itself
is called a number.
So in this case, our number is nine.
Seven plus one, is it so the sum is single digit number, so we call it as the annable if the sum is
too reasonable like it, plus 1917 and here the last digit of the sum.
Seven is a number.
Similarly, four plus 1913 and digital some history, so the number is three.
Eight plus one is 15 here.
Five is the last digit of the sum.
So five is the end number.
So this is the concept of a number.
Kerry or not getting numbers, if the sum of numbers is 10 or more than 10, then the numbers are all
getting numbers.
For example, if we add seven and eight, we get 15 here.
15 is a two digit number and is more than 10.
So seven and eight are called carry numbers.
Similarly, if we add eight and nine, we get 17.
It is more than 10, so eight and nine are called carry numbers.
Similarly, we are nine and six, we get 15 and 15 is more than 10, so nine and six are called getting
numbers, some are four and six is 10, and it is equal to 10.
So four and six are called getting numbers.
Some are five and six is 11.
It is more than 10, so five and six are called scary numbers, but some are four and three is seven,
which is less than 10.
So four and three are not getting numbers.
So if this obviously isn't done, then the numbers are called non carry numbers.
Similarly, some of five entries, eight, which is less than 10 survive.
And we are not getting numbers, some of it.
And one is nine, which is again, less than 10.
So eight were not noncareer numbers.
So this is a difference between getting numbers and not getting numbers.
If the same is true digit number and is 10 or more than 10, then the numbers are getting numbers.
And if the sum is less than 10, then the numbers are called noncareer numbers.
In order to do fast additions, we have to be very fast in writing and numbers, so let's practice and
numbers eight plus seven is 15 and number is five, seven plus three is 10 and number is zero eight
plus six is 14.
And nobody's fool APC's 11.
And nobody's one seven plus seven is 14 and nobody's fool.
Similarly, April 16 and every six, nine plus nine is 18, and nobody's eight, six plus six is 12
and number is two five, five is 10 again and number zero nine plus five is 14.
So four is the number.
We have to be very fast in writing and numbers.
So let's try to practice more.
Seven plus 1916.
Five plus eight is 13.
Four plus six is 10, four plus nine is 13.
Five plus seven is Dwil.
Six, seven is thirty eight, plus nine is 17.
Six plus nine is 15.
Surplus, 1916, four plus seven is 11, five plus nine is 14.
Eight plus seven is 15, seven plus raised in April, six is 14.
Eight plus three is 11, surplus, seven is 14, eight plus eight is 16, nine, nine is 18, six plus
six is 12, five plus five is 10.
And it was twistin.
You have to write these end points very, very fast.
If you are not able to read these end points very fast, then is better copied on these additions and
I don't know the answers to three times.
So with the help of a numbers, getting numbers are not getting numbers, we are going to learn additional
double numbers with the single number.
Now, in addition, mother, we always start earning from the Ritmo site, then moving to the left,
say, like nine Bluesfest Strel.
And now there is one Ghedi.
And this becomes three.
And here also we always start from the right will say April six is 14, one is scary, and then this
becomes why I not adding to the three to nine or forty six to eight is a very simple addition.
But I want to teach you a concept.
So try to understand that now this is a large matter.
So we are not going to move from right to left.
We will start from the left side and then we will move towards the right side.
Let's see how to do it.
We will start from the left side.
And who is alone?
There is no no over here.
But before dropping to over here, we will observe that the are on the right side.
Whether these are getting numbers or not, not three and nine are getting numbers.
So we will increase to by one.
Then it becomes three and then we will right the end point of three plus nine over here because three
plus nine is 12.
So end point is two.
So we will try to over here.
So this is a concept.
We will again start from the left side.
There's no number below four, so we can drop four over here.
But before dropping four over here, we will observe the pier on the right side.
Clearly, this is a carry number, so we will increase four by one.
So this becomes five and the seven, six and four is 14 and end point is four.
We will just ride and point over here.
So the answer becomes 54.
Now, this is just to expand a concept.
We will be using this concept to add more digit numbers.
Now, let's try to add these numbers.
We will start from three, but there is no number over here, so we have to just right three wheel.
But before adding three, we will absorb this seven and nine.
Seven and nine are getting numbers.
So we will increase three by one and then we will ride the end number of seven and nine.
That is 16.
So it will become six only S.A.M..
There's no number over here for five.
So we can ride five over here.
But before riding five, we will observe the pier on the road side two and six are not getting numbers
because the summer of 2006 is eight, which is a non carry number.
So we will ride five as it is.
We will not increase by one.
Now we will add 26 and we will ride down over here.
So 58 is the answer.
Similarly here also because there's no number over here.
So we can ride to over here.
But before riding to.
The numbers on the right side are six and eight, and they are getting numbers, so we will increase
two by one.
So that means it becomes three and six and it is 14.
So four is the number nine, but six and five are getting numbers.
So we will write ten instead of nine and some of six and five is 11.
So our number is one.
Similarly here, five and nine are getting numbers, so we will write nine for it and five plus nine
is 14.
So this will be four.
Now, we will try to write very fast.
Just we will observe the rightmost bill, if it is occurring more, then we will increase this number.
So this becomes eight, six plus four is Denon and nobody zero.
G and Ed are getting hammered, so instead of seven, we will eight and replace it is 11, so we will
write and point as one.
Seven and five are getting numbers, so instead of eight, we will rate nine.
And seven plus five is 12.
So and nobody's to.
Now, six in four are getting no survival rate nine.
And zero is the end point here.
Seven and eight are getting numbers instead of nine, we will right then and seven plus eight is 15.
So five is the animal.
No, nine and seven are getting numbers, so instead of three, we will write four and nine plus seven
is 16.
So six is the and number.
Here, Radian6 are getting numbers in.
We will write three, and it was successful in the four assignable here, seven and five were getting
numbers instead of eight, we will rate nine, seven plus five as well.
So twizzle and number here, three and seven are getting numbers.
So we will write five, four, four and three plus seven is Denso and number is zero.
Here, eight and four are getting numbers, so instead of five, we will write six and eight for four.
Well, so too is the number, so nine and seven are getting numbers.
So instead of six, we will write for seven.
And Niebla, 1716, so we'll just six Aweil.
So this is the technique to add numbers.
We will apply this technique to more digit numbers in the next little.
And now there's a task for you to propose more problems.
And answers are also given to you.
We will continue with more storms in the next lecture, so me in the next lecture.
