You're talking like it is impossible to divide 0 by 4 and its not. You wouldn't and couldn't get negative by that operation and obviously nitrates could not be negative.

Results say nitrates are 0, then they're 0.

But dividing the 0 result by 4 is 0 still 0. So either way the result is 0, 0 nitrates, whatever. You know 4 into 0 is 0 so theres no need to do the math. 0 is 0.

Just because you are dividing into 0 by 4 doesn't mean it needs to be less than 0 or something, I honestly can't figure out your negative talk and such. Just because its division doesn't mean the answer has to less than the 'result' (in this case).

Its really simple, its just a simple math equation. You don't need to go less than 0 if your result was 0 (just speaking in this case if it even needed to be done). Its just that each result would be divided by 4 in this case of the testing to achieve the correct level of nitrates. Dividing 0 by 4 does not change the results. 0=0 It is not impossible, it isn't inaccurate.

Again, I never said it was inaccurate. Those are your words not mine. In this case it's impossible, as I've already said in a test situation it's impossible to get anything less than 0. So, unless you can achieve a negative nitrate it's impossible to divide the 0 result by 4 and recieve any other number than 0, thus never changing the result of the test result of 0, making it impossible to ( in my example) to divide it by 4, because the test would remain at 0.
