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).
What is 6x plus 3 equals x plus 8?
This is an equivalence relation that contains elements of the natural numbers together with an element (denoted by the symbol x) that is defined by some extension of N.
Is 87 a natural number?
Since a natural number is defined as a whole, non-negative number, 87 would indeed be a natural number.
Is -a a natural number?
No. Natural numbers are 0, 1, 2, 3 ... If a was defined to be a negative integer, then -a would equal a natural number. But -a is a variable with a sign, not a natural number.
How is a rational number defined?
A rational number is a continuous quantity that is a quotient of two integers in which the second integer is a natural number. Rational numbers include the integers as well as non-integers such as fractions and decimals. Rational numbers are the direct result of the arithmetical operation of division.

Is the element cadmium natural or synthetic?
Cadmium is a natural chemical element.
Is uranium a natural element?
Yes, uranium is a natural but radioactive element.
Is lithium a natural or synthetic element?
Lithium is a natural element that is found in various minerals and salts in the Earth's crust. It is not a synthetic element.
Why Giuseppe Peano remove the zero to natural numbers?
In 1889 Peano published his version of a set of axioms for arithmetic. In his original version the first natural number was 1, rather than 0. Other natural numbers were defined by the unary "successor" function.Although the exclusion of 0 made little difference for the definition of natural numbers, 0 is also the additive identity of all natural numbers [ n + 0 = n = 0 + n ]. It was easier to develop a consistent theory for the set of natural numbers if this key element was included in the set.
What is the difference between an element and a native element?
Elements can either be synthetic or natural. Synthetic elements are made artificially in laboratories, while natural elements exist in their natural state in nature. Natural elements can further be defined as native elements. These elements exist in their uncombined state.
Is yttrium natural or synthetic?
Yttrium is a natural element found in the Earth's crust. It is not a synthetic element.
Is magnesium natural element?
Magnesium is is a natural element. It stays as salts in the nature.
Is rutherfordium a natural element?
Yes, it is a natural element. It is named after scientist Rutherford.
Is argon a man made or natural element?
Argon is a natural element found in the air.
Is nickel a natural element?
Yes nickel is a natural element not synthesized in a nuclear reactor or similar.
Is gold a natural element found on Earth?
Yes, gold is a natural element found on Earth.
