About & Prerequisite

This tutorial is primarily created for students who are new to algebra and algebraic identities. (Class 9 especially). Students are expected to remember few very important, frequently used algebraic identities but it is not easy for everyone to remember. Hence, it is always good to learn a very simple method to generate the output of these identities.

Pascal’s triangle has been explained and used in this tutorial.
