Real numbers are all numbers that you can get as a solution to a question.
Basically all numbers are real numbers if you can do whatever you want with it and get it as the answer.
I know this sounds like all numbers but there are number which dot not have solutions like square root of a minus number.For example of you type in root of -25 it will give you error
