Mathematics - Abstract Algebra 0
Many algebraic structures rely on binary operations, which take two objects as their input and combine them into a single object as output, like addition and multiplication do.
Abstract: Abstract algebra studies general structures such as groups, rings, and fields, and it emphasizes patterns, axioms, and proof rather than computation alone. It is also a strong bridge to applications in computer science, especially coding theory and cryptography, which many introductory texts use as motivation.
