Thank you for the opportunity to help you with your question!

 

ASSOCIATIVE ADDITION PROPERTY

In an addition problem, the position of the parenthesis doesn't matter. a+(b+c)=(a+b) + c


DISTRIBUTIVE =a(b+c)= ab=ac


 COMMUTATIVE ADDITION  PROPERTY=In an addition problem, you can rearrange the #s because the order doesn't matter

 Commutative multiplication=in a multiplication problem, the order doesn't matter. 

9X3=3X9

 ASSOCIATIVE  MULTIPLICATION=In a multiplication property, the position of the parenthesis doesn't matter

 IDENTITY property =The sum of zero and a # is that number. 
5+0=5

 Identity property of multiplication of 1 =the product of any # and 1 is that number
5X1=5

 

 Inverse property of addition=Every # has an additive inverse such that the # plus its inverse = 0
-100+100=0

 

 Inverse property (multiplication)Every # has a multiplicative inverse- the number time its inverse = 1


 Multiplication of -1 property=The product of any # and -1 is its additive inverse
2 x -1 = -2

Zero propert=

The product of any number and zero = 0
4 X 0=0


Symmetrical property

If a=b, then b=a; the equal sign works both ways


 Reflexive property=Every number equals itself

x=x


 Transitive  property=a=b and b=c, then a=c; Skip the middle 



Please let me know if you need any clarification. I'm always happy to answer your questions.
