(01) AboutEst. at PCCOER

MathX is the mathematics club of PCCOER. We think in patterns, argue in proofs and meet every week to chase problems that don't come with an answer key.

(a)TalksFaculty, alumni and guests on the maths behind engineering.

(b)CompetitionsIntegration bees, puzzle hunts and inter-college contests.

(c)Study circlesSmall groups working through one idea at a time.

Every idea has a shape.

(02) Notation

01 / 04Summation
Adding infinitely many things and getting something finite.
