Russian Adverbs
I've noticed that in Russian the adverb forms of adjectives always seem to follow a pattern.

Examples:
Хороший (adjective) Хорошо (adverb)
Плохой (adjective) Плохо (adverb)
Быстрый (adjective) Быстро (adverb)

It would seem that if you remove the adjective ending (ий, ый, or ой) and replace it with о then it changes the adjective into an adverb. Is this the case with lots of Russian adjectives? Is this a rule that I can usually follow? Or does it only apply to certain words?

Any insight would be helpful!

Russian Adverbs

Плохой (adjective) >>>>> Плохо (adverb)

Answer

Usually, but not always... Let's see:
1. replace adjective ending with O
 Examples:
веселый - весело, легкий - легко, смулый - смело, умелый - умело

2. replace adjective ending with E (usually these adjective look like participles) 
Examples:
Искренний - искренне, угрожающий - угрожающе, вызывающий - вызывающе, 

3 if adjective has ending -cкий, -цкий, -ический, then you have to replace it with И and in some cases add По- at the beginning of adverb.
Examples:
Немецкий - по-немецки, детский - по-детски, вражеский - вражески, геройский - геройски, фактисеский - фактически.

We've got three common rules with different ending (O, E, И)

Answer

Not only with "о". Look here:
неуклюжий >>>>> неуклюже
дружеский >>>>> дружески
пеший >>>>> пешком

Answer

This rule is often used, but does not always. We have many other rules which transform different parts of speech to adverb.
