## Different easy approach to Arithmetic

Authored by Mr Sridharan R

### Clearly an enchanting arithmetic book for further studies

Mathematics is an important subject without which we cannot imagine the modern world of science and technology. In mathematics, arithmetic is the back bone of mathematical sciences. Here we deal with some basic concepts of arithmetic and their applications which you will also feel enchanting and make more interesting to read a lot. The approach could be different than normal.This book is written in a simple language with examples, and definitions for easy understanding of the readers from various backgrounds. We hope this book will provide a better understanding of concepts in arithmetic.
