What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped in multiplication does not change the product (e.g., (ab)c = a(bc)).

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal (e.g., x + 2 = 5), while an inequality shows that one expression is greater than or less than another (e.g., x + 2 < 5).
