Different sets of numbers have different properties. For example,
The set of counting numbers is closed under addition but not under subtraction.
The set of integers is closed under addition, subtraction and multiplication but not under division.
Rational numbers are closed under all four basic operations of arithmetic, but not for square roots.
A set S is "closed" with respect to operation # if whenever x and y are any two elements of S, then x#y is also in S. y = 0 is excluded for division.
So, the answer depends on what you mean by "number".

What are the properties of the operation rational number?
Any number or decimal number that can be expressed as fraction is rational.
What are the properties of addition for elementary?
The relevant properties are the commutative property, the associative property, and the property of zero (i.e., if you add zero to a number you get the same number again).
Which properties can help you find the missing number?
none
What would the most efficient number of insulation layers be?
It is not simply a question of the number of layers but the properties of each layer.
What are the number properties?
properties that are number
Why do isotope have the same chemical properties?
Isotopes of an element have the same number of protons, which determines the element's chemical properties. The differing number of neutrons in isotopes does not significantly affect the element's chemical behavior.
What is the phone number of the Historical Properties in Battle Creek Michigan?
The phone number of the Historical Properties is: 269-962-5037.
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
What is a number that specifies certain properties of electrons?
quantum number
What is the phone number of the Anchorage Historic Properties in Anchorage Alaska?
The phone number of the Anchorage Historic Properties is: 907-274-3600.
What is the phone number of the Gulf Of Marine Properties in Portland Maine?
The phone number of the Gulf Of Marine Properties is: 207-228-1690.

How can properties help me add whole numbers and decimals?
Without properties, you cannot have a number system. Without a number system, there is nothing to add.
How is the periodicity of properties dependent upon the number of protons in an atom?
The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.
Why do istopes have different physical properties but same chemical properties?
They have similar chemical properties because isotopes of an element have the same number of electrons as an atom of that element. The electron arrangement is the same owing to same chemical properties. However they have different numbers of neutrons, which affects the mass number. Mass number determines the physical properties such as boiling/melting/density etc.
