I've just done it about 10 times, each time picking a random number, got me everytime

your end number should always be a multiple of 9

There's only certain numbers you can achieve (if you can add and subtract correctly) and if you look at the grid all those numbers have the same "gift" on them.

The only way it would get the answer wrong is if you got your sum wrong!

S'alright, worked it out now... Multiples of 9 ffs!

Thats played with my head that.

Ha, I was thinking it was a load of shite and didn't work, then I re-did my sums and discovered that 12-1-2 is not infact 8!!!

What a nob!!!

If you subtract the second digit of any two digit number it will take it back to a multiple of 10 (eg 25-5=20)

The 9 times table starts 1 behind, then 2, then 3 and so on as follows:
1x10 = 10 | 1x9 = 9 | 1 behind
2x10 = 20 | 2x9 = 18 | 2 behind
3x10 = 30 | 3x9 = 27 | 3 behind

So after subtracting the second digit and going back to the nearest multiple of 10, you subtract the first number which is always the difference between the 10 and 9 times table, so that takes it back to the nearest 9 which makes it much less obvious what is going on.

A slight twist that I haven't seen before, usually these things use the rule that the two digits of all the multiples of 9 add up to 9.
