3. The answer would always be a multiple of 9. This can be explained. Lets say the first digit is represented by x and the second digit by y. In order to get the first number, the formula would be 10x+y. And to add the digits its x+y. Which means to say that if you were to take 10x +y - (x+y) = 10x + y - x - y, the answer would be 9x. Therefore the answer would always be a multiple of 9.

4. to add on to mervin's answer as u can c that all the multiple of 9 have the same symbol so whatever the answer is it will always be the same symbol and the website keeps changing the symbol to avoid any suspicion.

5. ya i noticed the 27 first b4 the rest

6. cuz u wake up early and do

7. Erm I totally Don't get how it works honestly I tried lots of weird ways like putting my mouse over a number for a long time while thinking of other numbers then making it give me a wrong answer although I have found that it was very hard and that the numbers keep on changing so i had to calculate faster than the Flashlight...But I still don't get siddharth explanation I am so Confused! >.<

8. nvr mind tchr will surely help u understand better

9. Yeah I agree to Siddharth and Mervin's answer just that the other symbols are there to confuse you. :)

10. Yup, like whatever the number, ab-a+b always results in a multiple of nine...

11. I agree to jia en, eugene, siddharth and mervin's answer
but i saw this somewhere before in my primary school
i remember this as the answer can only give u multiples of nine
no matter what answer you put
but now it is easier for me to remember this :D

12. About the same as the ones that they wrote on top of my post.

13. same as the top

14. See this is why I should not have commented first -.-

15. 6.59 am LOL

16. The answer is a always a multiple of nine and all of the multiples of nine in the chart have the same symbol. After you try once they change the the symbols of all the numbers but the multiples of nine would have the same new symbol. So it is able to show you the correct answer.

17. The number is always the multiple of 9 then in the chart then all the symbols of the multiples of nine is the same.

18. Why all of you so smart one? I have no idea how you guys do it and how found out.....I am so confused ergghh!! or wait did you guys just go copying the first person's answer?

19. u can even do it for any 3 digit-number until u r left with 1 digit number. the answer will always be 9

20. when numbers are evaluated in this method you will always end up with a multiple of 9 the multiples are from 9 to 81 you can that all of their symbols are the SAME thus ending up with the SAME answer.
