Closure Property Worksheets
What is the Closure Property? (In Algebra) The term closure is a term that is used extensively in many fields. In the field of mathematics, closure is applied in many subbranches. The property states that when you perform any operation (like an arithmetic one) on any two numbers from the same set, the result will be another number in the same set. For instance, if we multiply two numbers from a set of even numbers, the answer will always be an even number. However, this property is only valid for a few conditions and not all of them.

Basic Lesson
Demonstrates how to determine if a set is closed through a rule system. A set is considered closed, under an operation, if the operation on two elements of the set produces another element of the set. If an element outside the set is created, then the operation is not closed.

Intermediate Lesson
Explores how to use the same concept in a visual set. If we divide one even number and one odd number and the answer is even than the property is not closed.
