It is indeed true that zero is a real number. Now give a simple step-by-step explanation for why zero is a real number.
Why is Zero a Real Number?
- The number 0 is a whole number.
- All the whole numbers are integers. Therefore, zero is an integer.
- All of the integrs are rational numbers. Therefore, zero is a rational number.
- Any rational number is automatically a real number. Therefore, we can conclude that 0 is indeed a real number.
Example of a Number that is not Real:
The square root of -1 is an example of a number that is not real. This is because there is no number that when multiplied by itself gives -1. Such numbers are also known as complex or imaginary numbers.
Since the number 0 has nothing to do with the imaginary number square root of -1 we can safely say that 0 is indeed a real number.
