I get 9:)

Nine. All of them add up to nine, don't they? Good game.

9 Multiply by 3. Then Add 3, Multiply with 3 You'll get a 2 digit no. or a Three digit. Add the digits 3 x 3 = 9 9 + 3 = 12 12 x 3 = 36 3 + 6 = 9

9 cool! :)

I did and I got the infinity sign. Can you tell me why?

I also get 9.

Nine. Zomg magic. :D

It's a simple math trick that takes advantage of the pecular characteristic of the multiplication tables for the number 9. I learned the following trick in grade school from my teacher to help me remember my 9's in the multiplication table: Using the number 7 for example: Subtract one from 7. The result will be the first digit of the final answer, in this case 6. Now subtract 6 from 9. The result will be the second digit of the final answer, in this case 3. Put them together and you have 63. If you pull out your fancy calculator and punch in 7 times 9, you can see that the result is indeed 63. To check your final answer to see if you made an error, add the two numbers together. You should always get 9. In this case, 6 + 3 = 9. For the numbers 1 through 9 in the multiplication table, you get the following numbers, with an easily identifiable pattern: 1: 9 2: 18 3: 27 4: 36 5: 45 6: 54 7: 63 8: 72 9: 81 10: 90 This process also works for the number 10 as well (which is why I listed it above), but the rule for multiplying by 10 (add a zero) is even simpler, so I never even consider using this rule of multiplying by nine for the number 10. This rule does NOT work for numbers higher than 10. In fact, the question should have "or a Three digit." removed to make it 100% correct.

9. By the way, my favorite number was 7.

Nine...it's magicalness :D

i think that It dependes on which numbers are your favorite numbers so that you can get your answer

9, I see why you only let us pick a number 1-9.:)
