A whole number is not a set of any kind and so cannot be a subset of rational numbers.
Composite numbers.Example: 17- factors of 17...1 and 17- This is a prime number.Example: 18- factors of 18...1,2,3,6,9,18- This is a composite number.
You can add a period, and a zero, after the whole number. Or you can just consider the whole numbers themselves a special kind of "decimal number".
There are more composite numbers than prime numbers, but there is no prime or composite number so great that you can't find a greater one of either kind.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.
No. An integer is a kind of number - a whole number - but not all numbers are integers. For example, a half is a number but it is not an integer.
No. Although the count of either kind of number is infinite, the cardinality of irrational numbers is an order of infinity greater than for the set of rational numbers.
Only even numbers are divisible by two. If you have an odd number, for example 3, and divide by two, you will get 1 with a remander of 1.
Whole numbers with more than two factors.
The number twenty-five is not the same number as thirteen because they are each one of a kind and numbers are the the same as any other numbers. They are the same as numbers but not the same in value. 25 is greater than 13 by 12.
All positive whole numbers over 1 can be classified either as prime or composite numbers. Those which are not prime are composite numbers, that is, numbers which are composed of several different factors.
Yes it can, but it depends on what kind of variable and how it relates to the whole number.
