what are real numbers?

Question

provide examples

Answer 1

A real number is any number, any integer, rational number, or irrational number. Any number you can mash out on your number pad is real.

The only type of number which is not real is the square root of a negative number. For example, the square root of -4 (-4^1/2) would factor into the square root of 4 (4^1/2) times the square root of -1 (-1^1/2), the square root of 4 equals 2, and the square root of -1 equals i (imaginary). Therefore, the square root of -4 would equal 2i (an imaginary number).

Answer 2

They're the ones that you don't actually admit to.

Example:
It's One AM and you've been at your buddy's house since noon. You each drank fifteen beers. Since you live thirteen miles away from where you've been drinking, and you have no other way to get the car back home, you leave your buddy's house driving 85 MPH South, down a North one-way street. After you wrap your car around a telephone pole, the cop asks you "How much did you have to drink tonight?" Guaranteed your response will be "only two," even though the "real" number is fifteen.
