Okay, so this one freaked me out for a long time, and I was suspecting some maths trick behind it, but the solution comes from here.

Take any two digit number. In our examples let's do the following numbers:
10, 72 and 97

Then you add them up and substract the result from the original number:
1+0=1; 10-1=9
7+2=9; 72-9=36
9+7=16, 97-16=81

Now what is common in the final number? They are multiples of 9. (yes, yes, I know, you can try all the numbers, but trust me, the result will always be a multiple of 9.)

Now looka t the screen and go through all the multiples of 9: 9, 18, 27, 36, 45, 64, 63, 72, 81 and 99 The symbols next to them are the same! So they will always give the correct reading. After each try the symbols are changed, but every 9th one will be the same.

What a good little trick!
