What is multiplication properties. example a number line that goes from 0-27. using numbers 6,7,8 and 9.

 They are the commutative, associative, multiplicative identity and distributive properties.

 Commutative property: For example 6 * 7 = 7 * 6;

 Associative Property:  For example (7 * 8) * 9 = 7 * (8 * 9);

 Multiplicative Identity Property: For example 6 * 1 = 6 or, 1 * 6 = 6;

 Distributive property:  For example 6 * ( 7 + 8) = 6 * 7 + 6 * 8 or, ( 7 + 8) * 6 = 7 * 6 + 8 * 6.
