No, it is not a natural number. It is not a whole, positive integer.
yes, 3 is a natural number. any positive number is.
Yes. The square of an integer is just the number times itself. For any two whole numbers that are multiplied, the answer is always an integer (i.e. no decimals).
-13 is rational and an integer.
It isn't. A negative integer is always smaller than a positive integer. Look at the numbers on a number line, in standard format. If a number is further to the right than another number, it is greater. The number further to the left is smaller.
Yes, the absolute value of an integer is always a natural number or zero. The absolute value measures the distance of a number from zero on the number line, which is always non-negative. Therefore, while positive integers and zero are considered natural numbers in some definitions, the absolute value of any integer will always be a natural number or zero.
It is a natural number and an integer.
It is not a natural number but it is an integer and a real number.
Not necessarily. The difference between a = 7 & b = 7 is 0, and that is not a natural number.
Real numbers consist of all numbers except complex numbers. Every integer is a natural number but every rational number is not a natural number as well as an integer. So, the answer to the question is integer.
5 is a natural number, as it is an integer greater than zero. It is a whole number, an integer, and a rational number.
No, -20 is not a natural number. It is an integer.
No.
Any integer above starting at and including zero is a natural number. Anything below zero is not.
No, it is not a natural number. It is not a whole, positive integer.
