No. Negative integers are not natural numbers. And mathematicians are divided about zero.
No. All whole numbers are integers.
Certainly depending on the problem regarding whole numbers which has not been given.
They are the only integers in that range with exactly two factors.
At least one of the integers is negative.
The integers are all the natural numbers and their negatives and zero. So 5 is a natural number and negative 5 is its negative. That makes it an integer.
The number system consists of real numbers. Real numbers are further divided into rational numbers and irrational numbers. Rational numbers consist of numbers(1-9) and integers(1.5, 3.7, 70.7, etc.) Irrational numbers are complex numbers(square roots of few numbers)
Whole numbers do not contain decimals or fractions because they are integers in the form of: 0 1 2 3 4 5 6 7 .... etc
15
If they already know what they are why do you need to explain to them?
They mean that if you subtract one of the two digit numbers from another then that is the difference. The numbers in the question are usually smallest first so you can't subtract like that. In these questions you may change the order of the numbers.
The product of two integers is found by multiplying them. Eg. the product of 5 and 3 is 15.
How do you have numbers what. Can you explain better
