A Third Math Sign - not just positive or negative Answered
I was thinking about a random thing the other week. We have positive and negative signs in widespread and ubiquitous use in mathematics. What if we had a third sign?
The number line would look like the one in the picture. It's not even a line anymore.
Since I am absolutely dumbfounded as to how even the basic operations would play out in this type of system (although I have a rough idea for addition and subtraction), and nor do I know what the possible applications for a redundant sign could be, I'm just putting this here.
Got ideas? Fire away.
