What is the finger trick to help you solve the 9 facts?

Place a finger down for the number you are multiplying by 9. Count the fingers to the left of the finger you put down. That is the product of the tens place. Count the fingers to the right of the finger you put down. That number is the product for the ones place. Both of the numbers together is your answer.
