Mathematicians are often interested in whether or not certain sets have particular properties under a given operation. One reason that mathematicians were interested in this was so that they could determine when equations would have solutions. If a set under a given operation has certain general properties, then we can solve linear equations in that set, for example. There are several important properties that a set may or may not satisfy under a particular operation. A property is a certain rule that holds if it is true for all elements of a set under the given operation and a property does not hold if there is at least one pair of elements that do not follow the property under the given operation.

Integers strictly larger than zero are positive integers and integers strictly less than zero are negative integers. Note that the set of integers is not closed under the operation of division. Using the properties of integers above, show that set of integers is closed under the operation of subtraction.

Are integers closed under division

Consider the following situations:. Closure Property MathBitsNotebook. A set is closed under an operation if and only if the operation on any two elements of the set produces another element of the same set. If the operation produces even one element outside of the set, the operation is not closed. Since 2. There are also other examples that fail. All that is needed is ONE counterexample to prove closure fails. The set of real numbers is closed under multiplication. If you multiply two real numbers, you will get another real number. There is no possibility of ever getting anything other than another real number.
