debt

That money doesn't "disappear" like the example image though. It has just been shuffled around between parties.

the guy with negative apples had some apple debt he needed to pay off, and it was quicker to just write -

>Height above/below a reference point (e.g. sea level)
>Manometric pressure
>Heat to or from a system

Lay some yardsticks on the ground. Face forward. Go forward one yard. Turn around 180 degrees. Go forward one yard. You just effectively went backward one yard relative to your last position, and ended up in the same place. 1+(-1) = 0. Boom. Soon shitposting will become an endangered species I pray.

In the real world the indebted would have to find a third party apple though. Only to have there still be apples existing afterwards.

That's not the same thing. Rates of change and differences in measurements like height don't make actual object simply not be once you're done mathing them together.

No, but they are crucial for math to work. Should equations and physical computation STOP the second you encounter a negative number?

>No
For fuck's sake, just because there's no such thing as negative mass doesn't mean "negativeness" can't be applied to other things in reality, you chimps.

Only as much as positive numbers do.
It's not like any real world apple has the platonic form of the positive number 1 floating over it.
