Is Pi a real number?

Is 1 a whole number?

The whole numbers are set of real numbers that includes zero and all positive counting numbers. Whereas, excludes fractions, negative integers, fractions, and decimals. Since, 1 is a positive integer and is a counting number. Hence, it is considered to be a whole number.

Is 1 a prime number?

Using this definition, 1 can be divided by 1 and the number itself, which is also 1, so 1 is a prime number. However, modern mathematicians define a number as prime if it is divided by exactly two numbers. For example: 13 is prime, because it can be divided by exactly two numbers, 1 and 13.

Are 0 and 1 a prime number?

Number 1 has positive divisors as 1 and itself and it must have only two positive factors. Now, for 1, the number of positive factors is only one i.e., 1 itself. So, number one is not a prime number and one is not a composite number also. Therefore, 0 and 1 both are not a prime number.
