Trick : Multiplication by 6

1.Add half of the neighbor to each digit.

2.If the starting digit is odd, add 5.

Example: 
6 × 357 = 2142

Working right to left, 
7 has no neighbor, add 5 (since 7 is odd) = 12. Write 2, carry the 1.


5 + half of 7 (3) + 5 (since the starting digit 5 is odd) + 1 (carried) = 14. Write 4, carry the 1.


3 + half of 5 (2) + 5 (since 3 is odd) + 1 (carried) = 11. Write 1, carry 1.


0 + half of 3 (1) + 1 (carried) = 2. Write 2.
