The powers of 10
from which the
difference is
calculated is called
the Base.

5. www.vedicmathsofindia.com
78 x 73 = ?
These two digits are
neither closer to 10 nor
100.

6. www.vedicmathsofindia.com
So, we will take base
10 x 8 = 80
(since 78 & 73 are closer to 80)

7. www.vedicmathsofindia.com
78 x 73 = ?
So, here base is 80.
Hence the difference
between the base and
numbers are -2 and -7
respectively

We will write this as
78 -2
X 73 -7
-----------------

9. www.vedicmathsofindia.com
Step 1: Multiply -2 x -7
78 -2
X 73 -7
---------------
4Carry 1

10. 78 -2
X 73 -7
---------------
4Carry 1
For base Below 100 , there will be 1 digit on right
side and for base above 100, it is 2 digit, prefix 0
when answer is single digit in step 1 for Base
above 100.

Step 2: Cross add 78 + -7
78 -2
X 73 -7
- - - - - - - - - - - -
71 4

12. www.vedicmathsofindia.com
Step 3: Multiply 71 by 8
(since we have taken base
as 80. i.e. 10 x 8)
71 4
X 8
568

13. www.vedicmathsofindia.com
Step 4:
71 4
X 8
568
+ Carried 1
569

So we will get this
answer
5694

So,
78
X 73
----------
5694
