where does the comma go ?

grammar not grammer. You put the comma anywhere your little heart desires. Grammar is power. Don't be a semi colon when you can be a full colon.

Grammar, like spelling, seems to be in a constant state of flux.  When I was going to school I was taught "yes, always."  However, I use a comma before "and" when I have a series that could mean two different things, only one of which I intend.  For example: I have two patterns, one of them is black and white and the other one is red and green.  I might state this as: "I have two patterns: black and white, and red and green."  Leaving out the comma before the "and" might lead one to believe that both patterns had all four colours.  (My apologies if that's not the best example, there are probably better ways to word that particular sentence which avoid the comma dilemma altogether, but I hope it gives you an idea of my meaning.)

It's okay, but instead of "This" say what you mean - what does "this" refer to? - Oh, and ditch the comma.  You aren't combining two independent clauses, so you really don't need it.

Hi, You are using too many commas.  In your first sentence you can take out all the commas.  That sentence doesn't need any.  The second sentence needs the commas you have placed taken out also.  In the third sentence the word "the" that you are referring to should be  the word their instead and it shouldn't be capitalized either.

A comma separates the last two items in a series even though these items are linked by a conjunction. This comma was once considered optional, but the trend is to make it mandatory, especially in technical and business English. Leaving it out can cause confusion and misinterpretation.

terri, you need to learn to understand, he has written this question almost perfectly, just missed out a comma, but big deal!. The English probably "borrowed" the word Holland from one language, and Dutch from another, I'd like to know if I'm wrong though, good question, by the way.

next to the 0(zero key)is the hyphen-   push the hyphen key and shift at the same time.\n\nso instead of -, you will get _.\n\nYAY!

Well, the sentence has more issues than just the commas.  "It took a while" and "eventually" are somewhat redundant.  If you want to use both then say, "It took awhile, but he eventually noticed me."

Either with a comma or without a comma; either is correct.

None of them.  \n\nA, C, and D are grammatically incorrect.\n\nB is wrong because the pronoun is not capitalized correctly.

None because:\n\n1.) There are robots all around making our lives easier.\n(took out comma)\n\n2.) There are robots all around, which make our lives easier.\n(added comma)\n*Note: This seems to be incorrect, so I will say that the answer MAY be #2, depending on how you were taught English.\n\n3.) There are robots all around; they make our lives easier.\n(changed comma into semicolon)

It is a noun or pronoun which renames another noun or pronoun immediately preceding it.\n\nA nonessential appositive (you don't need it for the sentence to make sense) should be set off by commas.\n\nExample: My favorite class, English, is always fun!\n\nIn this example English (a noun) renames my favorite class (another noun).

I think the commas after Professor are not needed. Just making an educated guess, though.
