Clever little trick - but sussed it too after a few gos.....

very cool

Nice trick - solved it on go 2 by not actually picking a number.(Never could do what I was told!)

We do these all the time in Mensa.

Don't read further if you don't want to know:

================================

The basic theory is like an accounting transposition. If you had up a column of two or more digit numbers, and the sum is off by a multiple of 9, then you have a transposition error somewhere, e.g.: 310 may be written as 130 in error (difference of 180, divisible by nine).

The initial computation always result in a multiple of nine. Then the magic symbol chart has the same symbol at those multiples.

Magic!

No, Mathgic!
