This is so easy, the result will always be a multiple of 9. Just check the symbols, all multiples of 9 have the same symbol (exept 90 and 99, cause the result can never be that high).

No magic involved, just pure math

[Elandril]

Yes math is always great.

[Goenk]

Even if it is just math, it's really fun, isn't it?

[rjcali]

even though theres no magic its good for a larf

It occassionally got lucky with me, but most of the time it was wrong, lol.

That is impossible Jito ;-D

Itґs is ALWAYS correct. Try it again, bro. ^^

[Kinlaadare]

Aye, this is always true...

lil and fast proof :

a and b are your digits, 0<=a<10 and 0<=b<10

10*a+b-(a+b)=9*a...

Nuttin' ta add

Note : This is true whatever are your two numbers taken in Z (for those who don't know what is Z, it's the integer (positive and negative) number group)

Edit : Ooops typo

[Jito463]

Nope, not impossible. It was definitely wrong on several occasions. My math was correct, it's math was off the mark.

[Kinlaadare]

It's mathematicaly impossible.

I never said it's 'computerly' impossible
