I Enjoyed this thread and thought that I'd contribute.
1. Multiply 2 single digits to form a product
2. Continue to multiply the resulting product by a single digit of your choice until said product is 7 digits (or more in length)
3. Circle one of the non-zero digits of the product (for me to guess) and post the remaining digits in any order.
4. I will post your circled digit..
Two questions: How? and give a mathematically valid reason for % accuracy.
