Could someone explain to me the simple rules of adding subtracting multiplying dividing Normal and lognormal distributions?

My profs notes are very messy and it's really hard to keep up w/ also the supplied book was published in 1964 w/ no updates. Possibly a site?

I just need simple rules to follow which will make it easier for me to solve. thanks again
