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)
