   Is zero a real number?

   • Hi Joe, Zero is a number; in fact, it is a real number. It is on the number line right between 1 and -1. You can add, subtract, and multiply with 0 and get real answers. You can divide numbers into zero and get a real answer, zero. You can't say anything like that about infinity. It is not on the number line and you can't do computations with it.

   How do we know if a number is zero?

   • Our understanding of zero is profound when you consider this fact: We don’t often, or perhaps ever, encounter zero in nature. Numbers like one, two, and three have a counterpart. We can see one light flash on. We can hear two beeps from a car horn. But zero? It requires us to recognize that the absence of something is a thing in and of itself.
