Special Multiplication by 9

BONJOUR TOUT LE MONDE
I like Mathematics so much and I love to take Vedic maths
Classes all over the world. I am taking French Classes also
Since I have finished Delf A1 Exams.After practising
Vedic maths I can able to give many methods of Multiplication
Unusual. So I feel that if all the Children in the World practise this
Amazing System then they will not have night mare before their
Maths Exam and they also start to like the subject. If a Child Masters
in Mathematics then he can Master in any Subject since Maths is the
head of all Sciences. I would like to thank Mr.Gaurav Tekriwal
for his Continued Support and Encouragement. I am sure that We
can take Vedic maths to all parts of the World with his Continuing
Support. Here are some methods of Multiplication by 9.
Multiplication of any digit number in descending order with 9 :
( 1 ) 21 X 9
We will get 3 parts of the answer.
= 1 / 8 / 9 = 189
First part of the answer is obtained by subtracting 1 from the
1st digit of the Multiplicand. Second part of the answer is just
write one 8.Third part of the answer is the Compliment of the
last digit of the Multiplicand from 10.
( 2 ) 321 X 9
We will get 3 parts of the answer.
= 2 / 88 / 9 = 2889
( 3 ) 7654 X 9
We will get 3 parts of the answer
= 6 / 888 / 6 = 68886
Main rule is to remember is
If you multiply 2 digit number by 9 --- Centre part is one 8
If you multiply 3 digit number by 9 --- Centre part is two 8’s
If you multiply 4 digit number by 9 --- Centre part is three 8’s
And go on and on.
