3x9=3x3x3=27 Not sure what you mean by break apart. One way to do it in your head if you need to and don't just know it is 27 is to say 3x10=30 which is easy because adding tens is easy for most people. Now 3x9 is one less 3 then 3x10. That is to say, think of 3x9 as 9 threes, and 10x3 as 10 threes. So 30-3 is 27
