If OK take a piece of paper
and write any three digit number.

Add the three digits together
to get a sum.

Substract the sum from Your
number.

Write down the result.

Now you strike off any digit
from the result.

Enter the remaining digits in
the following boxes. And click the "Find" Button. (Eg. if your answer is 185
and you strike off 8, enter 1 in first box leave middle box blank
and enter 5
in the third box. You can enter the numbers in any order) I
will tell the number you strike off !!..
