people. i repeat myself again:
the law of non-contradiction, for example, is that math? the law of causation, is that math?
as for your examples, you are confusing units with negativity when it comes to atoms. subtract one able from two, you are moving one apple, you are not adding minus one apple. show me a photo of -1 apple. you might as well say walking backwards is negative velocity. this is a way of thinking about things, but it's semantics.
math is one way logic can be applied, but there is a difference between pure math and applied math. everyone knows this. you've even seen it yourself. adding one raindrop to one raindrop gives one raindrop: but twice the mass. but add one apple to one apple, you'll get two apples but they won't both have the same mass, so 1+1=stupid decimal. you need logic separate from math, base don observation, to see the difference.
math is all well and good, but you need something to apply it accurately before it describes anything. or are you saying any math description must automatically be true? in this case, the pull of 'gravity' is 2006739070942m/s/s. that's bs. why? nothing to do with mass, it's to do with observation.
think. please.
