The use of commas is determined by some rules, and through experience with writing down your thoughts. Here are a couple rules for when you should use a comma:
Commas give use spots to pause, to breathe. Many people try to cram in many parts into one sentence and then, add a ton of commas. Other people insert a comma in the wrong places--for example (wrong): My brother, and I went to the store. A comma here splits up the compound subject, when it shouldn't and is incorrect.
Have you ever visited Gettysburg Pennsylvania. Were does the commas go.
The dog hates me, therfore I do not touch it.
No, commas are not used to enclose restrictive phrases and clauses. Restrictive phrases and clauses provide essential information about the noun they are modifying and should not be separated by commas.
The correct placement of commas would be: "Do you go to school, Shaina?" The comma is placed after "school" and before the name "Shaina" to create a pause between the question and the person being addressed.
Use inverted commas when indicating direct speech, quoting someone, or highlighting specific words or phrases. They can also be used to denote irony or skepticism.
Have you ever visited Gettysburg Pennsylvania. Were does the commas go.
commas go after question marks
After "Roseville"
In between the 20 and the three zeroes. So it should look like this: 20,000.
Only when you are listing should you use commas between adjectives. Hope this helped :)
British style places commas and periods that are not part of the quoted material outside of the quotation marks. Also, in technical applications or when discussing coding, punctuation that is not part of a text string should be placed outside of the quotes. Placing commas and periods inside the quotes implies that they are part of the string to be displayed.
The whole sentence is incorrect, it should read:- "Paloma did not make it to work because her car broke down on the freeway" This sentence requires no commas.
The commas should be placed before and after "Seema" for direct address. The sentence would read: "I wonder, Seema, if you've thought through the implications of your actions."
1,000,000
37251285 = 37,251,285
10,000,000
In general, a sentence should have 1-2 commas for optimal clarity and readability. Overusing commas can make a sentence confusing, while not using enough can make it difficult to understand.
