Here on RMRK, we've all passed elementary school. We all know that 1+1=2 and 2+2=4. Pretty basic math.
That's what I thought too, until I started an argument with one of my college professors. He believed that one plus one does not equal two. Unfortunately, one can't argue too much with one's college professor without getting into trouble, so I dropped the arguement and let it slide.
Needless to say I thought the guy was insane, but when I later checked up on this, I found that there were numerous other people who also believed that one plus one does not always equal two. Some mathematicians scientifically "proved" that one plus one did not equal two but rather 1.997 (although their "proof" is highly questionable). Others had more plausable reasons, such as where c=speed of light, 1c +1c = 1c (1+1=1), and used examples like 1g + 1kg = 1.001kg, since no variables are defined in the expression 1+1=2. But in all the theories, the point remained the same: one plus one does not always equal two.
So what do you people think? Does one plus one equal two or does it not (and why)?
