Este documento presenta un taller sobre conjuntos y operaciones entre ellos. Se definen tres conjuntos A, B y C y se piden resolver ejercicios aplicando leyes como la conmutativa, asociativa, distributiva, identidad, complemento y de Morgan. Se demuestran propiedades como A union A = A, A intersección A = A, y (A union B)' = A' intersección B'.
