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

21 x 23 = ?
These two digits are
neither closer to 10 nor
100.

6. www.vedicmathsofindia.com
So, we will take base
10 x 2 = 20
(since 21 & 23 are closer to 20)

7. www.vedicmathsofindia.com
21 x 23 = ?
So, here base is 20.
Hence the difference
between the base and
numbers are +1 and +3
respectively
