Closure property under multiplication states that any two rational numbers' product will be a rational number, i.e. if a and b are any two rational numbers, ab will also be a rational number. Example: (3/2) × (2/9) = 1/3.
The set of integers is not closed under the operation of division. because when one intger is divided by another integer,the result is not always an integer. For example, 4 and 9 both are integers, but 4 ÷ 9 = 4/9 is not an integer. Q.
Do you know why division is not under closure property? The division is not under closure property because division by zero is not defined. We can also say that except '0' all numbers are closed under division.
If the division of two numbers from a set always produces a number in the set, we have closure under division. The set of whole numbers are not closed under division, and the set of integers are not closed under division because they both produce fractions.
This means that dividing two natural numbers doesn't necessarily result in another natural number. If you divide 3 by 2, for example, you get 1.5, which is not a natural number, thereby demonstrating that the set of natural numbers is not closed under division.
Hence, the set of natural numbers is not closed under division. Hence, we can say that the set of natural numbers is closed under addition and multiplication but not under subtraction and division.
Closure Property A natural number is closed under addition and multiplication. This means that adding or multiplying two natural numbers results in a natural number. However, for subtraction and division, natural numbers do not follow closure property. When a and b are two natural numbers, a+b is also a natural number.
Closure Property The product of any two real numbers will result in a real number. This is known as the closure property of multiplication.
The closure property of multiplication states that when any two elements of a set are multiplied, their product will also be present in that set. The closure property formula for multiplication for a given set S is: ∀ a, b ∈ S ⇒ a × b ∈ S.
The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S. Here are some examples of sets that are closed under addition: Natural Numbers (ℕ): ∀ a, b ∈ ℕ ⇒ a + b ∈ ℕ Whole Numbers (W): ∀ a, b ∈ W ⇒ a + b ∈ W.
