Spread the word!!!.. ALL pens need to be made like this!
One plus one can be two (mathematically), one (linguistically), more than one (biologically), or zero (melancholy).

The beauty of mathematics and numbers - through Euler’s identity, which ties together the imaginary number, the exponential, pi, 1 and 0. The imaginary number is derived out of necessity in algebra. The exponential number was invented for calculus for logarithmic and exponential functions, pi is essential in tying together geometry, and 1 and 0 are……well, everything. This equation ties together algebra, calculus, geometry, and basic numerology. And it was DISCOVERED. Not invented. That should say something, about the nature of numbers and math to who we are. Math has an unreasonable amount of utility in this universe, especially for something that we essentially INVENTED out of our own heads. It should tell us that there are connections out there that we might not even be aware of. That have not yet been discovered. How incredibly little we know about the world and universe we inhabit.

Why Does 0.999… = 1?
Consider the real number that is represented by a zero and a decimal point, followed by a never-ending string of nines:
0.99999…
It may come as a surprise when you first learn the fact that this real number is actually EQUAL to the integer 1. A common argument that is often given to show this is as follows. If S = 0.999…, then 10*S = 9.999… so by subtracting the first equation from the second, we get
9*S = 9.000…
and therefore S=1. Here’s another argument. The number 0.1111… = 1/9, so if we multiply both sides by 9, we obtain 0.9999…=1.
