In this lecture, we will be learning addition of double to double digit numbers using laterite addition
technique or spermatic.
Now, since we are familiar with our numbers and carry on on getting numbers, so this technique becomes
very easy for us, again, we will start from the left side and move toward the right side.
Four plus two is six.
But before writing six over here, we will observe the number.
On the right side, they are getting numbers.
So that means we will increase six by one number.
So it becomes seven and some of nine entries will.
And we will write a number here, so answer becomes 72 samea, this is six plus nine, but eight in
favor getting numbers.
So instead of writing nine here, we will write 10, where we will increase nine by one number and now
eight plus five is 13.
Just idle and no way.
So only for the left, most people will write the complete number.
Otherwise, we will always read the end numbers.
Five plus six is 11, but nine and seven are getting numbers, so instead of riding 11, we will ride.
Well.
And now nine 11 is 16 and six is the end number, so we will write six or eight.
No evidence Barkov time.
We will try to read the answers very fast if you do it mentally without speaking.
You can read these additions very, very fast.
Here's seven and six are Kerry numbers, so four plus one is five in 05, we will ride six and seven
plus six is 13.
Will just Rydal and number 63 is answer since seven and four Kerry numbers.
So eight plus one is nine instead of nine, we will write 10.
And seven plus for 11, so it's a number over here.
So hundred and one is the answer in this case, 20 Dockerty numbers.
So five to seven, but instead of seven, we will write eight and now Blasé Distin and its end number
is zero.
So it is zero where?
Now, this time, seven plus one is not a a number because almost seven and one is eight and it is less
than 10, so no need to increase.
Six plus nine is 15 and 15 will be as it is because seven in one unknown carry numbers and there are
some seven plus one eight as it is now.
In this case, seven and nine are getting numbers.
So two plus these five in 05 we will reach six and seven plus nine is 16 and a number is six.
So six over.
Now, we will try to do it very, very fast, and if along with me you try to do it mentally, it will
be very good by watching me just observe the nine and seven are getting a muscle instead of one plus
four or five, we will ride six and seven.
Nine is 16.
So we just ride six over here and know five.
Annita again.
Guerena So two plus seven, nine instead of nine we will ride 10 and it was five is 13.
So just ride three.
Forensics are getting numbers eight plus one is nine instead of nine, we will return and six plus four
is Denso and number is zero.
Now two and three are not getting numbers, so we will not increase the sum.
April seven is 15.
We just wrote 15 instead of increasing it and two places, five, six plus name again on getting numbers
because there some is less than 10.
So five to seven, we will not increase the of five and two and six and three gives us nine non-voter.
Nine are getting numbers.
So some of seven plus three which is ten now becomes eleven and four plus nine is 13 and number is three.
A few more practice problems, but this time without speaking, we are going to do it.
So just by observing, we can give answer.
Now, here is a small task for you.
There are more problems over the next.
Well, problems you have to solve.
And others are giving away his.
