2 - 8 = -6
-6 is not a natural number.
2/8 = 1/4
1/4 is not a natural number.

What are the mathematical operations to be used involving numbers?
They are addition, subtraction, division and multiplication
Order of operations-directed numbers?
parentheses, exponents, multiplication, division, addition, and subtraction.
Performing of operations on series of numbers?
An operation on a series of numbers is when you use amongst others addition, subtraction, multiplication and division. Mathematics decided the order of operations is to work out the sums in the brackets first, then exponents, then multiplications and division and finally addition and subtraction.
What are the fundamental operations in decimal numbers?
The fundamental operations are operations in arithmetic: addition, subtraction, multiplication and division. These are the same whatever the base of the number system.
What are the numbers in division mutliplication addition subtraction?
You can have counting number in multiplication and addition. All integers are in multiplication, addition and subtraction. All rational numbers are in all four. Real numbers, complex numbers and other larger sets are consistent with the four operations.
What is arithmetic?
Arithmetic is the process of applying the four basic operations: addition, subtraction, multiplication and division to numbers.
What are the mathematical operations to be used involving numbers?
They are addition, subtraction, division and multiplication
Order of operations-directed numbers?
parentheses, exponents, multiplication, division, addition, and subtraction.
Why do the natural numbers need an extension?
While natural numbers are closed with respect to addition and mulitplication, they are missing the additive identity (zero). Furthermore, they are not closed with respect to two of the fundamental operations of arithmetic: subtraction and division.

The fundamental operations are operations in arithmetic: addition, subtraction, multiplication and division. These are the same whatever the base of the number system.
Are rational numbers are closed under addition subtraction division or multiplication?
The set of rational numbers is closed under all 4 basic operations.
Give ten examples of natural number are closed under subtraction and division?
You can give hundreds of examples, but a single counterexample shows that natural numbers are NOT closed under subtraction or division. For example, 1 - 2 is NOT a natural number, and 1 / 2 is NOT a natural number.
What are the numbers in division mutliplication addition subtraction?
You can have counting number in multiplication and addition. All integers are in multiplication, addition and subtraction. All rational numbers are in all four. Real numbers, complex numbers and other larger sets are consistent with the four operations.
What is operations on sign numbers?
Most operations may be carried out on signed numbers: addition, subtraction, multiplication, division, exponentiation, trigonometric functions and so on. For some operation the domain may need to be restricted (or the codomain extended).
What are the fundamental operations on whole numbers and decimal?
The fundamental operations on whole numbers and decimals are addition, subtraction, division, and multiplication. However, multiplying and dividing decimals is a bit more complicated because you have to count decimal points to get an accurate answer.
Is closure exist for whole numbers under subtraction and division for integers?
Whole numbers subtraction: YesDivision integers: No.
