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

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

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.
