the proofs that I find don't stand up, because first addition...

1 + -2= 1 - 2

yes, but the two being subtracted is actually a positive number, but the DIFFERENCE(a word used for subtraction) being shown the difference is that two is one more than, higher or away from one, therefore from one's point of view he has to look higher to see the two, therefore his gain on the two is made up of the figure negative one, but what is a negative gain, a gain is a gain, and a loss is a loss. Yesterday my friend, who's a police-man was told by his boss "Great job Parker! We gained so many losses today!" He's joking, and it's funny because it doesn't make sense logicaly, but you can understand what he's implying, still it is a form of deception, but mathematics is built on logic, and it's creed is that, there is no deceptiveness in simple numbers, only complexness, thanks, the other proof is about negative space or volume, but you only can measure it positively, that's my thought clarifi?

A man went into a shoe store to buy a $12 pair of shoes. He handed the clerk a $20. It was early in the day and the clerk didn't have any $1 bills. He took the $20 and went to the restaurant next door, where he exchanged it for twenty $1s. He then gave the customer his change. Later that morning, the restaurant owner came to the clerk and said, "This is a counterfeit $20." The clerk apologized, took the phony $20 back, and gave the restaurant owner two good $10s. Not counting the cost of the shoes, how much did the shoe store lose?

I read this recently and have been stumped by it. I seem to get a different answer every time. What can you come up with?

Water is H2O
Carbon dioxide is Co2
Normal atmospheric air has oxogen, nitrogen, and carbon dioxide, plus some other stuff.
I know it is not just O2, which woiuld be pure oxogen.
I guess to make it easier I would request the answer be for sea level and about 29 degrees of atmospheric pressure.
This is my first question so be kind, no spam or BS.
