When you want to introduce a list
To replace the word and in compound sentences
Commas are for taking a break in a sentence, not as long as a full stop though. Usually you would use a comma to join two sentences together, only you'd put a claus such as only or however. Put the clauses either before or after the comma. Remember to use commas in lists, just not in between the last two things in the list, for that part you put and. Never Start A Sentence With And!
examples of how to use commas:
I bought potatoes, carrots, chocolate biscuits, chinese crackers and a huge pumpkin.
Mum, when do we get to go home, I'm famished(hungry).
In a sentence, you would put commas here:
I saw a penny in the street yesterday, and it was very shiny!
You put a comma instead of 'and' and periods, however, if there are more than two (2) compound items, one always places an 'and' INSTEAD of a comma before the last item. To wit:
My friend was angry, sweating and rude when he yelled at the bartender.
To be basic, whenever you pause naturally in a sentence (imagine saying it out loud) you put a comma.
It's not exactly that simple though, so here:

commas are ofter used to enclose words in a sentence, information that is not essential to the meaning of the sentence. Such words are preceded and followed by a comma. As an alternative explanation, commas are used to separate clauses - a dependent clause from an independent clause. So, an example would be "my cat, if you do not mind me saying so, ran up your tree". The main point is that "my cat ran up your tree" the rest of the sentence is not relevent to that action.

A common is not appropriate in the middle of a sentence. A common is also not appropriate when it breaks up an idea.

The comma should come before the word "but" when it is used to separate two independent clauses. For example: "I wanted to go to the store, but it started raining."
It would be appropriate to use a comma between compound subjects or compound verbs.
Yes, a comma should be placed before the word "too" when it is used at the end of a sentence to indicate "also" or "in addition." For example, "I enjoy hiking, too."
You use commas between items in a list, between the date and the year, and after the greeting in a friendly letter.

No, a comma before "as appropriate" is not necessary. It depends on the context of the sentence and whether it flows better with or without the comma.
the appropriate thing is a comma
The comma goes after the word 'because' when it is used at the beginning of a dependent clause, separating the clause from the main clause. For example: "I stayed inside, because it was raining."
Yes, a comma should be used after "which" when it introduces a nonrestrictive clause in a sentence.
No. After the word and comma can not be used, as it is grammatically inappropriate to use comma after conjunctions such as and, which are called coordinate conjunctions.
Yes, you should use a comma before "Jr." when writing a person's name to separate the person's last name from the suffix. For example, "John Smith, Jr."
