Agam and I found a new your number is...
Instead of always getting 5 in our method you should always get the number 9 once you finish.
Here is the method we discovered...
Think of a number
Add 10
Subtract 5
Add 4
And Subtract it by the first number.
We tried this method with a majority of 1, 2 and 3 digit numbers including...
4
Here is what we got...
4 + 10 = 14 - 5 = 9 + 4 = 13 - 4 = 9
23
And we got...
23 + 10 = 33 - 5 = 28 + 4 = 32 - 23 = 9
101
And we got...
101 + 10 = 111 - 5 = 106 + 4 = 110 - 101 = 9
We then tried many other 1, 2 and 3 digit numbers and then came to a conclusion that when you finish the method it will always equal 9.
