What you will learn

Understanding different number systems like Octal, Hexadecimal and Binary. How binary number system is used to represent values in memory of computer.

Understanding complement technique, signed integer represented using 2s complement in memory. Calculating range of values for signed and unsigned system.

How to perform addition and subtraction in different number system.

How the real numbers are represented using IEEE 754 single and double precision formats.

How to create a customised number system of your own.

Why take this course?

The main goal of this course is to teach the basics of Number Theory and how values are represented in the memory of computer. This is very basic knowledge that any programmer/ Computer Science student must posses. This course is to help all those aspiring programmers to build their sound fundamentals with Number Theory.

In order to understand how the information is stored and processed in the memory of computer and other digital systems, students must understand the core concept of Numbers, how they are represented in computer. Good grasp on this topic will make it easier for students to learn programming.

You will learn:

Basic concept of Number Theory.
Standard number systems - Octal, Hexadecimal, Binary.
How to convert number from any of these system to decimal and vice versa.
1s and 2s complement technique. Negative number representation using 2s complement technique.
How subtraction is done using 2s complement in the memory.
Real number representation using IEEE 754 standard (Single and Double precision).

Please do not enrol if you are:

Not interested of doing basic math calculations using pen and paper.
Expecting representations using graphics and animation, I did all the writings on the whiteboard. They are really easy to understand.

Feel free to ask questions in the Q/A section, you will find me always with you during the learning process.

Happy learning!

This class does provide the material without going into detail about why the number system conversion works. Also, the twos complement presentation is very weak. The offset of 127 for real number is not explained clearly, I kept watching hoping that I will get a better outcome from the next chapters but the explanation was weak and they data can be easily found for free on the web.

Good content, very well delivered and interesting topic. Some sections could be a little more detailed. Overall a very useful, clear and informative course.

Fantastic course on number theory! We worked with octal, hexadecimal, binary bases and real numbers. The videos on the 2's complement are really good! I find the quizzes very helpful to practice and solidify the information on the videos. Shibaji, you're a magnificent teacher! Thanks a lot for releasing this course!

Great introductory course to basic number systems including octal, binary, hexadecimal, and IEEE 754 systems.

Now I find the number system makes a lot more sense in how they work, from arithmetic to signed values. There are sections were things seemed to be odd, like 'where did that result come from?' but it helps if you pause the video at the moment you are trying to figure out. All in all, a great course.

Good course. Great approach to demonstrate how number systems as a whole work rather than only teach specific number systems. The progression is natural this way and I found myself being able to count naturally in binary after a while.

The course was fantastic. The instructor was indeed knowledgeable and willing to help students. The class materials were splendid and made this course enjoyable overall. I would strongly recommend Shibaji to any other student. Give this man a raise....Shibaji, You Rock...

Excellent course my rating is 5 out of 5 I am a Professor of an engineering college, I will recommend this course of my students. This is also helpful those who are working with programming, Thanks to Udemy recommending me such a wonderful course, Thanks to Mr SHIBAJI PAUL for a wonderful course design and with very lucid examples. This is works for me

I have completed more than 50% lectures of the course today and found it really absorbing. Mr. Shibaji Paul, you did a great job presenting this foundation course for aspiring programmers. The Instructor has created lots of Quizzes, almost after every lecture. Which is good to keep the students interested and engaged. Overall worthy of 5 Star rating. Very concise, practical approach and easy to understand. Great return on your investment. Strongly recommend! Especially for those who likes to play with numbers.

since i learned the number system as a topic in my modules at college, i can say that this course is detailed and easy to understand. you just need to know the basic maths to learn this. if you want a clear understanding of number systems, then i would recommend this course to you.. happy learning

Number systems are very well presented and easy to understand, because author do not rushes and shows many examples explaining even smallest steps. It is easy to follow even for people who are not great in mathematics.

1. Very good lecture. 2. Easy to grasp the idea. 3. Good way of presentation. 4. The best thing is recapitulation of the last lecture's gist, at starting of the current lecture.
