natural numbers are 1, 2, 3, 4, 5..........
whole numbers are natural numbers including 0, i.e., 0, 1, 2, 3, 4, 5..........
Difference of two natural numbers is not always a natural number.
For any two natural numbers a and b, a-b = natural number only when a>b.
Otherwise the result is a integer.
No, e.g. 6 - 10 = -4. -4 is negative, so it is not a natural number.
A natural number is a number which is positive and a whole number.
whole numbers can be also negative.
A "difference between" requires two things: there is only one - whole numbers - in the question.
7. The answer is simply to round DOWN half the difference (or halve the difference minus one)
No. Example: The difference of 2/5 & 1/3: 2/5 - 1/3 = 1/15 ∈ ℚ (is a rational number) ∉ ℕ (is not a natural number).
Yes.
Not necessarily. The difference between a = 7 & b = 7 is 0, and that is not a natural number.
A natural number is a counting number, such as 1, 2, 3. There are also known as whole numbers and integers. They can be infinitely large. A real number is a number, possibly a natural number, but more possibly not, because there are an infinite number of real numbers that lie between any two natural numbers, such as 1, 1.1, 1.11, 1.111, 111112, etc, ad infinitum. Real numbers can also be infinitely large.
No. For two reasons: 1) Negative numbers are not natural numbers 2) All natural numbers are rational numbers but the square root of 6 is an irrational number and thus cannot be a natural number.
Difference of two odd numbers is an even number. Adding an even number changes nothing.
No, since 2 is not divisible by three in the natural numbers.
The difference of their cubes is 4.
No. 5 and 2 are real numbers. Their difference, 3, is a rational number.
Yes, the difference of two whole numbers is always a whole number.
Yes. You know this is true because you learned a process-- an "algorithm"--for adding two numbers together, and if you start with two whole numbers, the result is also a whole number.
