RNT1.4. Ideals and Quotient Rings

Ring Theory: We define ideals in rings as an analogue of normal subgroups in group theory. We give a correspondence between (two-sided) ideals and kernels of homomorphisms using quotient rings. We also state the First Isomorphism Theorem for Rings and give examples.

Topology, Winding Numbers and Signed Area | Algebraic Calculus One | Wild Egg

Topology arises from a key property of the continuum as modelled by the rational numbers: that we have distinguished positive numbers (x greater than or equal to 0) which are closed under addition and multiplication. This is the starting point of notions of inside and outside. When we mov
