We know that in general we have $(J \cap K) + (J \cap I) \subset J \cap (K + I)$.

So in general you can do something that is called localising a ring at a prime ideal $P$ to produce a local ring

Just a remainder: here you can learn how to use TeX/MathJax in chat.

Yes, Thermodynamics....Statistical Mechanics--I don't even have a knowledge of the language these subjects use! :)

We've proved that ideals in a ring form a modular lattice.

Note that the sum of two ideals is just their sup and the intersection is their inf.

$$\sum_{i=1}^{st}1=\left(\sum_{i=1}^{s} 1\right)\left(\sum_{i=1}^t 1\right)$$

Let's go over it again then: $R := K[x,y], I = \langle x \rangle, K = \langle y \rangle, J = \langle x + y \rangle$.
