  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. 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! >.<

  12. 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.

  16. 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.
