Dear WookieeB,
Is 2 a number? It can be written many ways: 2 = 1 + 1 = 0.83 + 1.27 = 26 - 24, and probably a few others.
But it can also be written: 2 = 1 + 1/2 + 1/4 + 1/8 + … + (1/2)^n + ….. I. e., an infinite sum.
There was a time, hundreds of years ago, when mathematicians didn’t know how to deal with the number “0” (zero), so they just insisted it didn’t exist. There was also a time when mathematicians didn’t know how to deal with negative numbers or what we now call imaginary or complex numbers, so they just insisted they didn’t exist and left vast areas of mathematics unapproachable. Mathematicians now know how to deal with infinities and infinite sums in a great many contexts and to do so in a logically consistent manor. Your problem is not that you are ignorant, it is just that you are a couple of hundred years behind the times. But at least you are not an infinite number of years out of date.
