Hi Henry  


My grandpa loved card tricks and math tricks... one of his favorites was this one:

1. Think of a 3 digit number the only thing/rule is that the first digit is bigger than the last. (e.g. 300, and from now on lets call the three digits ABC)  
2. Subtract it's backward value (e.g. ABC - CBA = DEF)
3. To the total add it's backward value (e.g. DEF + FED)
4. Let me know when you have done this, I will tell you the total [Do not write the number on a reply, I will tell you the total as "magic"]


Edit: just in case anyone else has already done it, the total is 1089
