Fields are mathematical structures that satisfy certain properties, allowing for addition, subtraction, multiplication, and division. They are sets with two operations (addition and multiplication) that follow specific rules.
Think of a field as a playground where you can play different games like addition and multiplication. Just like in a playground, you have rules to follow while playing these games.
Ring: A ring is similar to a field but does not necessarily have multiplicative inverses for all elements.
Vector Space: A vector space is an example of a field where the operations of addition and scalar multiplication are defined.
Field Extension: A field extension is created by adding new elements to an existing field while preserving its original structure.
