Maybe you didn't follow instructions Kota
I've donde this more than ten times and it always returns the right answer...
I chose the following number 7699, jumbled --> 9796
subtraction: 9796 - 7699 = 2097
I circled number nine, jumbled ----> 702
Typed in 702 and fido answered 9
I guess the addition of your last number gives out the number you circled.
Let me see that again:
I chose the following number 3865, jumbled --> 8365
subtraction: 8365 - 3856 = 4509
I circled number five, jumbled ----> 094
Typed in 94 and fido answered 5!
Ok now I see, when the addition of your last number is greater than 9, then it subtracts. 9 - 4 = 5
Ok so what if you end up with the same digit (except for the zero of course)
1478, 4781, 4781 - 1478 = 3303, you should enter 303, 330, 33
fido's answer will be 3 always.
What if you end up with a 3 digit number with no zeros in it?
9732 - 2379 = 7353
circled number 5, jumble ---> 337
If I enter 357 then fido's answer is 3....I can't see the pattern
Ok I need some help with this
So cracking the code, so far
- remove the zeros
- if digits are all the same
- then output: the repeating digit
- else somewhere in here we must deal with the number 3,3,5,7 lol
- sum = sum of all digits
- if sum < 9
