Abhinav Prakash

Number theory is an interesting and vast field of mathematics. Sometimes it is also described as higher arithmetic. Hence, in this course, Abhinav Prakash focuses on clearing one's myths related to Number theory. In this course, he intends to provide unique ways to solve questions related to number theory which would help one to improve their efficiency. The lessons in this course are also beneficial to acquaint the vast knowledge required to solve the wide range of questions.  By taking up this course one would gain a better understanding of concepts pertaining to number theory. Some of the vital concepts which would be discussed in the course are the fundamentals of Reminder Theorem and Divisibility Rules, derivations of the divisibility rules, Fermat theorem, Euler's Number and Sum of Digit, concepts related to power cycles, arithmetic progression, geometric progression, harmonic progression and much more.

A thorough analysis of questions, book lists, planner, and much more: everything you need to know about SSC CGL, SSC CHSL and CPO examinations.

This lesson provides you a brief outline of all the aspects which this course will deal with. Abhinav takes you through the major objectives of taking up this course. Then he throws light on the topics which he will be coming up with on Number theory.

Overview of the Course: Gain an Understanding of Number theory with Examples

This lesson deals completely about the basic remainder theorem and certain concepts pertaining to divisibility rules.  As this unit starts Abhinav explains about the basic remainder theorem. Then he shifts his focus on explaining the divisibility rules of various numbers by using proper examples.

Know About Basic Remainder Theorem and Divisibility Rules

This lesson is in continuance with the previous, where the concepts which we came across on divisibility rules will be utilized to solve the questions on them. Abhinav has solved various questions and solves them using divisibility rules.

Solved Questions on Divisibility Rule

In this unit, one will come across derivations of divisibility rules. As the lesson instigates one will come across derivation for divisibility rule of the ​numbers 3 and 9. Then he takes you through derivation for divisibility rule of the numbers 2, 4 and 8. Finally, he explains the derivation for divisibility rule of the numbers 7, 11 and 13.

Understanding the Derivation of Divisibility Rules

This lesson helps one to gain insights into the concepts related to cyclicity in number theory. Using various examples he explains what cyclicity is and how is it found. Then he takes up some remainder questions and solves them by explaining each step.

Understanding power cycle of a number with examples

With worked out examples, the Fermat's Little Theorem is explained to quickly solve the remainder type questions in a matter of few seconds. This theorem is based on the concepts of basic remainder theorem and euler number.

In this lesson, one can learn about Base System and question relevant to this topic. It gives you an understanding of how to convert a number from  one base to another such as decimal to binary, octal or hexadecimal and vice versa. It also demonstrates how to apply basic operations like subtraction and addition on numbers from base different than decimal.

Base System

In this course, Abhinav has comprehensively covered almost all the important topics related to Number system. In this lesson, he covers a few more concepts relevant to this course such as finding whether a number is prime or not, HCF and LCM of fractions, and tricks to find whether a number is divisible or not.

Miscellaneous Concepts - Part I

This lesson is a continuation of the video - miscellaneous concepts on number theory. Abhinav explains the concepts of Prime factorization of a number and makes it easy to understand by solving examples.

Miscellaneous Concepts - Part II

In this lesson, Abhinav has included various types of questions based on the concepts of number theory and has shown the best way to appraoch them.

Number Theory - Question Bank I

Questions are what one is going to face in the exam. In this lesson more questions, related to the concepts explained earlier lessons, are solved in the best possible manner. Questions from this topic which have come in CAT exam in past years are also solved.

Number Theory - Question Bank II

Factorial is a very important and scoring topic. In this lesson, all the types of question related to finding the remainder of a factorial, the number of zeroes of a factorial, etc, have been covered by Abhinav.  ​

Questions Based On Factorial 1

This lesson is in continuation of the previous lesson, and here Abhinav has taken up few more questions pertaining to factorials and has given a step-wise approach to solve each one of them.

Questions Based on Factorials 2

In this lesson, Abhinav has explained the concepts related to counting of numbers. As this lesson starts, one will be coming across some important formulae which one should memorize to solve questions on the counting of numbers. Abhinav has taken up few more questions pertaining to factorials and has given a step-wise approach to solve each one of them.

Counting of Numbers

In this lesson, Abhinav Prakash will brief you few important techniques which one can utilize to find last two digit of a number. He also solves few examples to make us understand steps to solve such questions.

Finding Last Two Digit of a Number 1

Further to the previous lesson, here Abhinav continues explaining tricks to find last two digit of a number. He takes few more questions and explains how to approch such questins by solving them.
