## Description

**< Step-by-step explanation of more than 100 video lessons on Abstract Algebra: Group Theory>****<Instant reply to your questions asked during lessons>****<Weekly live talks on Abstract Algebra: Group Theory. You can raise your questions in a live session as well>****<Helping materials like notes, examples, and exercises>****<Solution of quizzes and assignments>**

This is an advanced level course of **Introduction to Abstract Algebra** with majors in **Group Theory**. Students who want to learn algebra at an advanced level, usually learn **Introduction to Abstract Algebra: Group Theory**. The course is offered for pure mathematics students in different universities around the world. However, the students who take the **Introduction to Abstract Algebra: Group Theory **course, are named super genius in **group theory.** Not so much difficult, but regular attention and interest can lead to the students in the right learning environment of mathematics. Many students around the world have their interest in learning **Introduction to Abstract Algebra: Group Theory** but they could't find any proper course or instructor.

Abstract Algebra is comprised of one of the main topics which are also called **Group theory**. Group Theory or Group is actually the name of the fundamental four properties of mathematics that are frequently used in real analysis. We actually establish a strong background of Group Theory by defining different concepts. Proof of theorems and solutions of many examples is one of the interesting parts while studying Group Theory.

This course is filmed on a whiteboard (8 hours) and Tablet (2 hours). The length of this course is 10 hours with more than 15 sections and 100 videos. Almost every content of Group Theory has been included in this course. The students have difficulties in understanding the theorem, especially in Group Theory. Theorems have been explained with proof and examples in this course. A number of examples and exercises make this course easy for every student, even those who are taking this course the first time.

I assure all my students that they will enjoy this course. But however, if they have any difficulty then they can discuss it with me. I will answer your every question with a prompt response. One thing I will ask you is that you must see the contents sections and some free preview videos before enrolling in this course.

## Who this course is for:

- Students who wants to learn algebra concepts on advance level

## Instructor

If there is a walking encyclopedia of Python, Data Science, Data Analysis, and Mathematics, then it should be called AD Chauhdry.

Ad Chauhdry is a researcher of Data Analytics for over 15 years in which he’s contributed articles in several scientific journals with good impact factors. His work also includes teaching data analytics to post-graduate students, so you can trust his teaching and research experience.

With Ad Chauhdry, you may jump into learning how to solve data analytic problems, and how to understand machine learning, deep learning, and solution to problems in data analysis and then transfer your skills into learning Python, Machine learning, and other applicable areas on Udemy. Ad Chauhdry reveals the secrets of maths and Calculus underlying so many things in economics, technology development, etc. If you want to see it for yourself, you have an excellent opportunity to get such things explained by an experienced data scientist, researcher, and educator – Ad.
