Andrew was given the following math problem to solve in front of the class: 3 x 14. He became extremely nervous because he had never practice two digit multiplication before. As he looked at the problem, he realized he could decompose the 14 to make it easier to multiply. He chose to split 14 into 10 and 4. He began working the problem out on the board:
3  x  14  =  3 x (10 + 4)  
(3 x 10) + (3 x 4)  
30  +  12  
42
What property of multiplication did Andrew use to solve the problem?

• Associative
• Commutative
• Distributive

• n= $2 because 9 x 2 is equal to 18
• n= $24 because 18 + 8 is equal to 18
• n = $3 because 9 x 3 is equal to 18
