The set of integers is closed under addition because the sum of any two integers is always an integer. This means that when you add two whole numbers, whether they are positive, negative, or zero, the result will still belong to the set of integers. For example, adding -3 and 5 results in 2, which is also an integer. Hence, this property ensures that no matter which integers are selected for addition, the outcome remains within the set of integers.
What else can I help you with?
Is the set of integers closed under addition?
Yes it is.
What is the set of whole numbers closed by?
If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.
Is the set of even integers closed under addition and multiplication?
Yes.
Is the set of negative integers is closed under addition?
No, the set of negative integers is not closed under addition. When you add two negative integers, the result is always a negative integer. However, if you add a negative integer and a positive integer, the result can be a positive integer, which is not in the set of negative integers. Thus, the set does not satisfy the closure property for addition.
Are all integers closed under addition?
Yes, all integers are closed under addition. This means that when you add any two integers together, the result is always another integer. For example, adding -3 and 5 yields 2, which is also an integer. Therefore, the set of integers is closed under the operation of addition.
Is the set of integers closed under addition?
Yes it is.
ARe odd integers not closed under addition?
That is correct, the set is not closed.
Under which operation is the set of odd integers closed?
addition
What is the set of whole numbers closed by?
If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.
Is the set of even integers closed under addition and multiplication?
Yes.
What does it mean if an integer is closed?
You don't say that "an integer is closed". It is the SET of integers which is closed UNDER A SPECIFIC OPERATION. For example, the SET of integers is closed under the operations of addition and multiplication. That means that an addition of two members of the set (two integers in this case) will again give you a member of the set (an integer in this case).
Is the set of negative integers is closed under addition?
No, the set of negative integers is not closed under addition. When you add two negative integers, the result is always a negative integer. However, if you add a negative integer and a positive integer, the result can be a positive integer, which is not in the set of negative integers. Thus, the set does not satisfy the closure property for addition.
Are all integers closed under addition?
Yes, all integers are closed under addition. This means that when you add any two integers together, the result is always another integer. For example, adding -3 and 5 yields 2, which is also an integer. Therefore, the set of integers is closed under the operation of addition.
Why the set of odd integers under addition is not a group?
Because the set is not closed under addition. If x and y are odd, then x + y is not odd.
Is the collection of integers closed under subraction?
Yes, the set of integers is closed under subtraction.
What gives an example of a set that is closed under addition?
An example of a set that is closed under addition is the set of all integers, denoted as (\mathbb{Z}). This means that if you take any two integers and add them together, the result will also be an integer. For instance, adding 3 and -5 results in -2, which is still an integer. Thus, (\mathbb{Z}) satisfies the property of closure under addition.
What is closed and not-closed under addition?
The set of even numbers is closed under addition, the set of odd numbers is not.
