The simplest way to do this under Calibre would be for both books to have a tag ‘algebra’ as well as tags ‘module theory’ and ‘linear algebra’ respectively. This tends to be the most flexible approach that I think many Calibre users end up adopting as it is the easiest.

The other way would be to make use of the heirarchical tags feature and have tags like ‘algebra.module theory’ and ‘algebra.linear algebra’. Using this approach both books would appear in the tag browser under the ‘algebra’ category with sub-categories of ‘module theory’ and ‘linear algebra’.
