@Pi Han Goh Hi! I have a doubt regarding one of your older questions. Where can I contact you ?

@Pi Han Goh

In the example given, you flipped only the first and last digit, the rest didn't get water imaged. Is that how it's meant? Or should all digits get water-imaged? In that case 120586 should become 982051, shouldn't it?

@Vishnu Bhagyanath – no. All the numbers are flipped. 1 becomes 1, 2 becomes 2, 0 becomes 0, 5 becomes 5, 8 becomes 8, 9 becomes 6.

Write it down in digital format on a piece of paper then turn the paper 180 degrees. And you will see why.

@Pi Han Goh – Oh, I see. It's a 180 degree rotation? I thought it was a water image / mirror image. Sorry.!
