No. For example, the square root of two plus (minus the square root of two) = 0, which is not an irrational number.

Closure property of addition in brief?

The closure property of addition says that if you add together any two numbers from a set, you will get another number from the same set. If the sum is not a number in the set, then the set is not closed under addition.


What is closure property addition of real numbers?

Real Numbers are said to be closed under addition because when you add two Real Numbers together the result will always be a Real Number.


Does every infinite set of whole numbers satisfy the closure property for addition?

No. Consider the set of odd integers.


Does the Commutative Property apply to addition of fractions?

Yes, it applies to even multiplication of fractions and rational and irrational numbers.


What is a example of Closure property of addition?

closure property is the sum or product of any two real numbers is also a real numbers.EXAMPLE,4 + 3 = 7 The sum is real number6 + 8 = 14add me in facebook.. lynnethurbina@yahoo.com =]


What are commutative propertyassociative property and closure propety?

Commutative property: a + b = b + a; example: 4 + 3 = 3 + 4 Associative property: (a + b) + c = a + (b + c); example: (1 + 2) + 3 = 1 + (2 + 3) Closure property: The sum of two numbers of certain sets is again a number of the set. All of the above apply similarly to addition of fractions, addition of real numbers, and multiplication of whole numbers, fractions, or real numbers.


What property represents a rational number added to a rational number gives a rational number answer?

The relevant property is the closure of the set of rational numbers under the operation of addition.


What is the intersection of the rational numbers and the irrational numbers?

Some would say that there is no intersection. However, if the set of irrational numbers is considered as a group then closure requires rationals to be a proper subset of the irrationals.


Is the set of irrational numbers closed under addition?

no it is not


Are even numbers closed for addition?

Yes, the sum of any two even numbers is an even number. This means they are closed under addition. Closure Property: For every even number a, for every even number b, a + b is an even number.


Is the set of irrational numbers closed under subtraction?

No; here's a counterexample to show that the set of irrational numbers is NOT closed under subtraction: pi - pi = 0. pi is an irrational number. If you subtract it from itself, you get zero, which is a rational number. Closure would require that the difference(answer) be an irrational number as well, which it isn't. Therefore the set of irrational numbers is NOT closed under subtraction.


What is the property of addition states that numbers can be added in any order?

It is the commutative property of addition.
