## What is number theory beginner?

A Friendly Introduction to Number Theory is an introductory undergraduate text designed to entice non-math majors into learning some mathematics, while at the same time teaching them how to think mathematically.

### Is number theory easy?

Introductory number theory is relatively easy. When I took it we covered primes, quadratic reciprocity, algebraic numbers, and lots of examples and relatively easy theorems. Most of the proofs we did in the class were very straightforward (wilsons & fermat’s little theorem, etc) and was not difficult at all.

#### Where should I start learning number theory?

For a typical undergraduate with not much exposure to Mathematics beyond high school, I would recommend starting with a book that essentially deals with topics in elementary Number Theory. By that I mean topics that are covered without any (or minimal) use of other branches of Mathematics (mostly Algebra or Analysis).

**What are the key ideas of number theory?**

Definition: Number theory is a branch of pure mathematics devoted to the study of the natural numbers and the integers. It is the study of the set of positive whole numbers which are usually called the set of natural numbers.

**Who is the father of number theory?**

Pierre de Fermat entered the mathematics scene in 17th century Europe. His work indicates that he had a similar fascination with the particular case of his last theorem of when 2 to that of the Babylonians. Fermat is credited as being the father of modern number theory, the queen of mathematics.

## Why is 28 the perfect number?

The proper factors of 28 are 1, 2, 4, 7 and 14. The sum of proper factors is 28. According to the definition of perfect numbers, 28 is a perfect number. therefore, 28 is a perfect number.

### How should I study number theory?

Number theory is a very vast topic and interesting too if you have the habit of sitting for hours with a pen, a paper and many practise problems….Study the following books:

- Niven & Zuckerman’s An Introduction to the Theory of Numbers.
- Summit & Foote’s Abstract algebra.
- Some book on Algebraic Number Theory.

#### At what grade do you learn number theory?

(Counting from 1 to 12.) I can go on and on. The basic stuff from Number Theory should be learned when the students study division without and with remainders, prime and composite numbers, that is, in GRADE SIX. There are a lot of problems pertaining to this topic, from very simple and up to quite sophisticated.

**What is the importance of studying number theory?**

Description: The number theory helps discover interesting relationships between different sorts of numbers and to prove that these are true . Number Theory is partly experimental and partly theoretical. Experimental part leads to questions and suggests ways to answer them.
