Video Transcript

a real number is any number that is not imaginary. Now, this is a very broad definition, but it really just means any number of not multiplied by I. So all of the natural numbers, like 123 those aerial lovers, all of the irrational numbers that is pi or E where they repeat on forever those aerial numbers, all of the rational numbers you might have 0.25 or 1/7. Those are all real numbers. All of these numbers are really unless they are multiplied by I. Basically, any number you can think of any number which has a useful use in everyday life is a real number, any number not multiplied by I Israel.
