MULTIPLICATION SHORT TRICKS
Lets start with Vedic Math by first learning simple Multiplication!!
ONE LINE MULTIPLICATION
Multiplication of :
AB
×CD
To solve this multiplication problem we have to follow 3 Steps which are as follows :-
Step – 1 : Multiply both terms on the left that is
=> B×D= a
Step – 2 : Cross multiply both terms and add
=> A×D + B×C = b
Step – 3 : Multiply both terms on right that is
=> A×C = c
NOW THE ANSWER IS JUST cba
NOTE : If any of a and b are two digit numbers then only units digit will be written rest will go to carry over ,c has to be written as it is.
Example 1 :
21
× 31
Step 1 :- 1 × 1 = 1 ; a=1
Step 2 :- 2 ×1 + 3 × 1 ; b=5
Step 3 :- 2 × 3 = 6 ; c=6
Final Answer
cba = 651
Example 2
42
×31
Step 1 :- 2×1= 2 ; a=2
Step 2 :- 4×1 + 3×2 = 10 ; b=10
Step 3 :- 4×3 = 12 ; c=12
So final answer is
+1
cba 12 0 2 (here 10 is double digit so I wrote 1 in carryover )
Final Answer = 1302
EXAMPLE 3
26
×52
a=12 ; b=34 ; c=10 (12 is double digit so I wrote 2 and ; 1 went carry over similarly 34 is double digit so I wrote 4 and ; 3 went to carry over )
+3 +1
10 4 2
Final Answer = 1352
EXAMPLE 4
75
×32
a=10 ; b= 29 (14 + 15) ; c= 21
+2 +1
21 9 0 (9+1 =10 so 1 also carryover as we have learned in junior classes)
+1
2 3 0 0
2400
Now you are good to go and practice a few more questions on your own for perfection and quick calculations.
