What is in Common for these number 3 4 5 6 7?
They are all whole numbers under ten; consecutive counting numbers.
How many factors under 1 does 12 have?
12 does not have any factors under 1, factors are whole numbers.
Can a greatest common factor be a rational number?
All factors are whole numbers and all whole numbers are rational numbers (a rational number is one which can be expressed as one integer over another integer, and whole numbers can be expressed as themselves over 1), thus all factors are rational numbers and so all greatest common factors are rational numbers. The set of whole numbers is a [proper] subset of the set of rational numbers: ℤ ⊂ ℚ
How can you express (12 4 16) as a multiple of a sum of whole numbers with no common factor?
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
Can decimals be multiples of whole numbers?
No.
Why are odd integers closed under multiplication but not under addition?
The numbers are not closed under addition because whole numbers, even integers, and natural numbers are closed.
Are the whole numbers closed under addition?
Yes.
What is the set of whole numbers closed by?
If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.
Are whole numbers closed under the operations of addition?
Yes. When you add any whole numbers you get another whole number. That is what closed means in this context. The answer is still a whole number.
What do you mean by 'whole number are closed under addition'?
The sum of any two whole numbers is a whole number.
What is an example of a counterexample for the difference of two whole numbers is a whole number?
There is no counterexample because the set of whole numbers is closed under addition (and subtraction).
What is always true about whole numbers?
They form a closed set under addition, subtraction or multiplication.
Are the whole numbers closed under addition if so explain?
Yes because being closed under an operation means that when the operation is performed on members of a set the result is also a member of the set, and when any two [members of the set of] whole numbers are added together the result of the addition is also a whole number which is, unsurprisingly, a member of the set of whole numbers.
What sets of numbers are closed under addition?
I know that whole numbers, integers, negative numbers, positive numbers, and even numbers are. Anyone feel free to correct me.
Do 0 and 3 have closure for addition?
A set of numbers is considered to be closed if and only if you take any 2 numbers and perform an operation on them, the answer will belong to the same set as the original numbers, than the set is closed under that operation. If you add any 2 real numbers, your answer will be a real number, so the real number set is closed under addition. If you divide any 2 whole numbers, your answer could be a repeating decimal, which is not a whole number, and is therefore not closed. As for 0 and 3, the most specific set they belong to is the whole numbers (0, 1, 2, 3...) If you add 0 and 3, your answer is 3, which is also a whole number. Therefore, yes 0 and 3 are closed under addition
What is an example of whole numbers are closed under division?
The whole numbers are not closed under division! The statement is false since, for example, 2/3 is not a whole number.
Why do whole number require an extension?
The set of whole numbers is not closed under division (by non-zero whole numbers).
