September 29, 2008 Summarize the Associative and Commutative Property. Use Examples! - **The Associative Property is when you can change the grouping symbols and it still creates the same answer. An example would be 2+(4+5)= 11 is equal to (2+4)+5= 11. It equals the same answer** - **The Commutative Property means that the order does not matter when you multiply or add two numbers. An example would be 2•3=3•2. Another example would be 2+3=3+2**
