Adword syntax correct? Want to be specific

[key phrase] -undesiredterm -junkterm

[silverbytes]

I want to be found only when users type a specific phrase and not when that phrase y follwed of other terms (as free! since I want to sell)

Is that syntax correct?

[key phrase] -undesiredterm -junkterm
[key phrase2] -undesiredterm2 -junkterm2

Thank you!

BTW what happens if my CPC is the cheapest but I have no others competitors... will my add show at top?

Thanks a lot for your clear answer FromRocky!

Finally: What happens if you build that list:

blue
widgets
big

You catch users searching for any of these terms in any combination? ie:

blue socks
my sister's nose is big

?

blue
widgets
big

You catch users searching for any of these terms in any combination?

Yes, you will catch any term or any combination of these terms but there are two problems with this list:

1. As I believe, common words such as blue, big, new, etc. are not allowed as a single keyword. Even they are allowed, these key words will be disabled in no time since they will generate thousands of page impressions in a minute.

2. You will get ton of clicks and these clicks are worthless.
