In multiplying by 9 take away 1 from the number you are multiplying. Then add up to 9. That will be your answer.
Example: 9 x 5 = 45. Take away 1 from 5 = 4 + ___ = 9. i.e. 4 & 5 makes 9.
So the answer is 45.
Example: 9 x 7 = 63. Take away 1 from 7 = 6 + ___ = 9. i.e. 6 & 3 makes 9.
So the answer is 63.
