Oh, right, thanks a lot, this makes a lot more sense! The substitution did help. (I'll accept your answer in ~5 minutes)

1/2024? Did you mean 1/1024?

@RahulNarain, Thanks a lot. This refreshed my memory.

comment How to easily divide numbers in scientific notation
Exactly, but then you need to round to approximate accurately. At least I'm suppose to. Maybe the "technical way" is different. You can keep it how it is, I'm just saying that the answer was 0.47 * 10^-6. Actually it was 4.7 * 10^-7

You might want to slightly alter your answer though. The division rounds to 0.47 * 10^-6. Since this is concerning science, it is quite important. :)

And 6.4 x 10^14? Is that 64 followed by 14 zeros. Perhaps 13?

comment Why do geometric sets such as $(\infty, x]$ never have infinity included?
@JasperLoy, I was being sarcastic. Didn't really come out like that though. Either way, I appreciate the answer. Unfortunately, I am not so experienced in mathematics as yourself. Therefore, I could not really make out what your answer was saying. I was not aware that because infinity wasn't in the geometric set that it could not be included. However, amWhy cleared it up for me.
