Answer: The closure property says that for any two rational numbers x and y, x – y is also a rational number. Thus, a result is a rational number. Consequently, the rational numbers are closed under subtraction.
Associative property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends (or the multiplicands).
Closure property For two rational numbers say x and y the results of addition, subtraction and multiplication operations give a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30.
The commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product. The commutative property of addition is expressed as A + B = B + A. The commutative property of multiplication is expressed as A × B = B × A.
The closure property formula for multiplication for a given set S is: ∀ a, b ∈ S ⇒ a × b ∈ S. Here are some examples of sets that are closed under multiplication: Natural Numbers (ℕ): ∀ a, b ∈ ℕ ⇒ a × b ∈ ℕ Whole Numbers (W): ∀ a, b ∈ W ⇒ a × b ∈ W.
Associative property is defined as, when more than two numbers are added or multiplied, the result remains the same, irrespective of how they are grouped. For instance, 2 × (7 × 6) = (2 × 7) × 6. 2 + (7 + 6) = (2 + 7) + 6.
The commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product. The commutative property of addition is expressed as A + B = B + A. The commutative property of multiplication is expressed as A × B = B × A.
The associative (grouping) property of addition and multiplication. If three or more numbers must be multiplied, it does not matter which two of the numbers are multiplied first. In the same way, if three or more numbers must be added, it does not matter which two of the numbers are added first.
