How does Lewis define acids and bases?
A Lewis acid is a molecule that accepts an electron pair, whereas a Lewis base is a molecule that donates an electron pair.
The implications of this definition are much wider than more traditional definitions.
For instance,
ammonia is a Lewis acid and boron trifluoride is a Lewis base in this example.

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.
