Why is zero not closed under the operation of whole numbers?
A set can be closed or not closed, not an individual element, such as zero. Furthermore, closure depends on the operation under consideration.
Is the set of all integers closed under the operation of multiplication?
Yes.
Is a set of natural numbers a group under the operation of addition?
No, a set of natural numbers is not a group under the operation of addition. For a set to be a group, it must satisfy four properties: closure, associativity, identity, and inverses. While the natural numbers are closed under addition and associative, there is no additive identity (0 is not included in the natural numbers) and no inverses (there is no natural number that can be added to another natural number to yield zero).
Is the set of positive integers a commutative group under the operation of addition?
No. It is not a group.
The set of real numbers are NOT closed under which operation?
Division, since you can't divide by zero.
Is the CFL closed under union operation?
Yes, the Canadian Football League (CFL) is not closed under union operation.
Why is zero not closed under the operation of whole numbers?
A set can be closed or not closed, not an individual element, such as zero. Furthermore, closure depends on the operation under consideration.
Is the set of irrational numbers a group under the operation of multiplication?
No. It is not even closed. sqrt(3)*sqrt(3) = 3 - which is rational.
Under which operation are natural numbers closed?
Addition.
Under which operation is the set of odd integers closed?
addition
Are natural numbers closed under the operation of multiplicaton?
yes
Are rational numbers closed under subtraction operation?
Yes, they are.
Is set of numbers closed under natural and subtraction?
Please clarify what set you are talking about. There are several sets of numbers. Also, "closed under..." should be followed by an operation; "natural" is not an operation.
Under what operation is the set of positive rational numbers not closed?
Subtraction.
Is the set of all integers closed under the operation of multiplication?
Yes.
What operation are whole numbers closed under?
l think multiplication
Is the set of non-deterministic polynomial time (NP) problems closed under the operation of union?
Yes, the set of non-deterministic polynomial time (NP) problems is closed under the operation of union.
