And this is not the first flash on this topic...

Stupid fat piglet...

Say the two-digit number you think about is ab.

So it's value is 10a + b.

Add a and b up, you get a + b.

Subtract the sum of a and b from the value of ab, you get (10a + b) - (a + b) = 9a.

So, whatever two digit number you think about, the result is 9a. It is divisible by 9!!!

So, the only trick here is to make all the numbers divisible by 9 the same icon... If you read the chart carefully, you'll notice that 9, 18, 27, 36, .....are all of the same icon.

Myth solved!!! I want two pairs of pig feet as reward, since pork are so expensive these days, and my ld likes roast pig feet while I cannot afford...
