The hierarchy of five most important topics are:

-Data Entry: Algebra is widely used in data entry.

-Interest rates: Basic algebra is used in calculating interest rates that are very useful in banking sector.

-Group Theory:

Almost all structures in abstract algebra are special cases of groups. Group Theory is a mathematical method by which aspects of molecules symmetry can be determined. The symmetry of a molecule reveals information about its properties (i.e., structure, spectra, polarity, and so on.

-Coding theory: Algebra is used in coding theory where we can send a personal message by coding it to protect from hacker.

-Cryptography:  Algebra is used in cryptography. Applications of cryptography are Network link encryption, wireless communication, digital signature etc.
