What is the basic formula of a redox reaction?
Well, we conceive of electrons, and oxidation numbers...
Oxygen is the quintessential oxidant .... it is conceived to GAIN electrons to form oxide ions...as shown....
For example, we could write the oxidation of dihydrogen gas as shown....
And this is a simple example of a redox equation. Confused yet? But all I have done is assign some oxidation numbers, and conserved mass and conserved charge....
Formal rules of assignment of oxidation numbers are given here....
Note that these are for reference...and not for learning off by heart....The best way is to learn these is to apply the given rigmarole to actual equations...for instance the oxidation of ammonia to nitrate...i.e. an eight electron oxidation with respect to nitrogen...

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
