This is a big question. I you enter 'relational algebra' in a search engine, you will find many sites which go over this. Wikipedia usually takes a very high level abstract approach. The link below seems fairly easy to understand.

Yes, relational algebra is non-procedural. Relational algebra comprises a collection of objects and operators on these objects. The operators may be used to specify which rows in the relations, or combinations or relations, are of interest but the operators do not in themselves specify any procedures or algorithms for identifying the items of interest.
