*Navasesh*

*Navasesh* is a general method of verification formulated in
Vedic mathematics.
This can be used to verify various mathematical operations such as Addition,
Subtraction, Multiplication etc.

Navasesh means ' * nine and its remainder* '.

Examples :

Navasesh of 23 ---> N(23) == N(2+3) == N(5) == 5

Navasesh of 82 ---> N(82) == N(8+2) == N(10) == N(1+0) == N(1) == 1

Navasesh of 49 ---> N(49) == N(4+9) == N(13) == N(1+3) == N(4) ==4

Navasesh of 105 ---> N(105) == N(1+0+5) == N(6) == 6

Addition

We know that 23 + 82 = 105

To verify :

N(23) + N(82) = N(5) + N(1) == N(5+1) == N(6) == 6

N(105) = N(6) == 6

Hence N(23) + N(82) = N(105)

Subtraction

We Know that 82 - 49 = 33

To verify :

N(82) - N(49) = N(1) - N(4) = N(1-4) == N(-3) == N(9-3) == N(6) == 6

( *Note**
that -3 here has been converted to 9-3 such that negative number
is eliminated*)

N(33) = N(3+3) == N(6) == 6

Hence N(82) - N(49) = N(33)

Multiplication

We know that 23 * 49 = 1127

To verify :

N(23) * N(49) = N(5) * N(4) ==N(5 * 4) ==N(20) = N(2) =2

N(1127) = N(1+1+2+7) = N(11) = N(2) =2

Hence N(23) * N(49) = N(1127)
