its always going to be a multiple of 9, no matter what number you chose

[bednobs]

and if you look, all the multiples of9 have the same symbol

Doh!

[redcrx]

try it with a few numbers at same time. (the symbols change each time its done)

youll find all the numbers have the same symbol (say 81.76.74.72,63,60 etc)

ie - 77 turns to 63
78 turns to 63
95 turns to 81
94 turns to 81

or as bednobs says lol all divisable by 9.

[Postdog]

9 is truly a magic number. It's possible to tell in an instant (maybe just a tad longer for big numbers) if a number can be divided by 9

I wouldn't mind, I'm not even blonde

[bednobs]

don't feel thick, it took me a couple of times to see it

[bednobs]

i think it's more likely your maths is wrong HW
