The associative property is when you can have parenthesis around one set of numbers and then you can put it around the other set to and get the same awnser for multiplication or addition. Like 2+(3+4)=(2+3)+4 or 2x(3x4)=(2x3)x4 The commutative property is when you can add or multiply numbers in any order and you can still get the same awnser. Like 2x3=3x2 or 2+3=3+2
