A number cannot be divided by zero. This is what mathematics today claim. But think again. Some years ago, it was not possible to have a number whose square results in a negative number. But then… we thought… why not? And now we have imaginary numbers with tons of applications. Zero is a useful tool and a curse. It represents “nothing”, which philosophically does not exist. But yet, we see it every day in our calculations. Everything is a matter of definition and the sentence “division by zero does not have any meaning” is such a case. If we decide to give meaning to it, then it will instantly have. In a sense we have already allowed division by zero.
