2: Associative property of Addition Words Changing the grouping of the numbers in a sum doesn't change the sum. Numbers (9+6)+2=9+(6+2) Algebra (a+b)+c=a(b+c)

3: Commutative Property of Multiplication Words In a product,you can multiply the number in any order. Numbers 8(-5)=-5(8) Algebra ab=ba

4: Associative Property of Multiplication Words Changing the group of the numbers in a product does not change the product. Numbers (3*10)*4=3*(10*4) Algebra (ab)c=a(bc)

5: Distributive Property | you need to put the numbers outside of the parentheses.
