This is the Associative Property, which deals with how the factors are grouped.
The Commutative Property is about moving factors around: a•b = b•a
Multiplicative Inverse is the idea that a • 1/a = 1. (That doesn’t work for 0, btw.)
Multiplication Property of Zero says “anything times 0 is 0.”
Multiplicative Identity is the idea that multiplying by 1 doesn’t change the value: 9•1 = 9
