Multiplication of 12 trick - using vedic maths
Take any number multiplication by 12.

Rules:
Rule 1 : Putting dot on both the sides. Dot value consider as a zero.
Rule 2 : Start from RHS dot, taking 2 digits at a time. Keep on adding, twice the second last digit and the last digit. If you have carry value, carry the next pair.
Rule 3 : Write answer in reverse order.

Example: 683 X 12
Rule 1 : .683.
Rule 2 : Take dot and 3, (2x3) + 0 = 6
Take next pair, 3 and 8, (2x8 ) + 3 = 19 = 9 (carry 1)
Take next pair, 8 and 6, (2x6) + 8 + 1 (carry) = 21 = 1 (carry 2)
Take next pair, 6 and dot, (2x0) + 6 + 2 = 8
Rule 3 : Write answer in backwards, 683 X 12 = 8196
