What else can I help you with?
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 all integers closed under the operation of multiplication?
Yes.
What binary operations have closure?
Closure depends on the set as much as it depends on the operation.For example, subtraction is closed for all integers but not for natural numbers. Division by a non-zero number is closed for the rational numbers but not integers.The set {1, 2, 3} is not closed under addition.
How are Integers combined?
All numbers - integers as well as non-integers - are combined using different mathematical operations. Some operators are binary: that is, they combine two numbers to produce a third; some are ternary (combine 3 to produce a fourth) and so on.The set of integers is closed under some operations: common examples are addition, subtraction, multiplication, exponentiation. But not all operators are: division, for example.
Is the set of all even integers closed with respect to addition?
Yes, it is.
What property do all nonzero numbers have that integers do not?
Of not being equal to zero. Also, of being closed under division.
Are rational numbers are closed under addition subtraction multiplication and division?
They are closed under all except that division by zero is not defined.
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.

Are rational numbers are closed under addition subtraction division or multiplication?
The set of rational numbers is closed under all 4 basic operations.
How are Integers combined?
All numbers - integers as well as non-integers - are combined using different mathematical operations. Some operators are binary: that is, they combine two numbers to produce a third; some are ternary (combine 3 to produce a fourth) and so on.The set of integers is closed under some operations: common examples are addition, subtraction, multiplication, exponentiation. But not all operators are: division, for example.
Why is rational numbers important?
Extending the set of all integers to included rational numbers give closure under division by non-zero integers. This allows equations such as 2x = 3 to be solved.
Is the set of all negative integers closed for operation of addition?
yes
Is the set of all even integers closed with respect to multiplication?
Yes, it is.
Is the set of all even integers closed with respect to addition?
Yes, it is.
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.
