ABSTRACT

A real number or a real value is one which can be experienced in real life. In fact, any value that can occur in our real life is indeed a real value. For example, it is possible to experience a temperature of (−22.4) degrees Fahrenheit. Hence the value (−22.4) is a real value. Take the example of a radio active element which emits, say, 623000000000 particles per unit of time. Hence the value 623000000000 is a real value.
