Mental Arithmetic (Posted on 2003-10-05) Difficulty: 3 of 5
I can multiply any three-digit number by 1667 in my head, usually in less than 10 seconds.

Also, to make it even more impressive, I come up with the digits of the result in proper order (not in reverse!)

How can I do this?

mohan says you will be given my answer soon enough, but I'm not certain how this site operates and who puts in my answer that I included with the question.

My screen of the question has a bottom line "this is your question. Add/Edit solution." Would someone advise what I am next supposed to do and when does my answer become visible to others.
