In trying to understand the ideal theory of a commutative ring, one quickly sees that it is important to first understand the prime ideals. We recall that a proper ideal P in a commutative ring R is prime if, whenever we have two elements a and b of R such that ab∈P, it follows that a∈P or b∈P; equivalently, P is a prime ideal if and only if the factor ring R/P is a domain.

It's intelligence in real time, but you have to know where you're looking and what you're after. Government sources told The Washington Post that the program had had little discernible impact on the government's ability to prevent terrorist [attacks].

Step 3. Listen and Correct (prooflisten): Learners listen to the spoken version of their text read aloud by the ABAIR voice. The user chooses the dialect they wish and the gender of the speaker. This provides not only exposure to native-like speech, but provides essentially a proof-listening tool which is a powerful aid for self-correction.

It will be like chum in the water, almost as invigorating to the crazies as bagging Dan Rather.
