Sets might contain an element that can be identified as an identity element under some binary operation. Performing the operation between the identity element and any arbitrary element in the set must result in the arbitrary element. An example is the identity element for the binary opera

Homomorphisms in abstract algebra
In this video we add some more definition to our toolbox before we go any further in our study into group theory and abstract algebra. The definition at hand is the homomorphism. A homomorphism is a function that maps the elements for one group to another whilst maintaining their structu

In this neat video, I’m connecting two unexpected worlds of linear algebra. Namely, I show that if T is a linear transformation with matrix A, then the matrix of T^-1 (the inverse transformation) is simply A^-1 (the inverse of a matrix). The proof itself is simply gorgeous and uses a combi
