Distributive Property: distribute base number, Commutative Property: changing order doesn't change answer, Associative Property: changing gouping doesn't change answer, Identity Property of Addition: any number plus zero equals that number, Identity Property of Multiplication: any number multiplied by one equals that nuber, Zero Property: any number multiplied by zero equals zero
Whichever one changes the order of the addends. a + b = b + a
the basic number properties in math are associative, commutative, and distributive associative: (for addition) a+(b+c)=(a+b)+c (for multiplication) a(bc)=(ab)c or a*(b*c)=(a*b)*c commutative: (for addition) a+b=b+a (for multiplication) a*b=b*a or ab=ba distributive: a(b+c)=ab+ac or a(b+c)=a*b + a*c
