I made this course as my first course at Udemy, It is a free course on number systems, expressing the values in each number system and converting values between them. This course does not required any pre-knowledge, even a laptop or PC. You can study any lecture in this course just with a paper and pencil, but you need to solve many examples on each topic in this course. I made many examples and questions to solve and I hope these are enough to understand number systems. I am also ready for any question from students.

I chose the number systems course as an Introduction about IT articles, and also an introduction to the new courses I will made which will be about programming and operation systems.

I know that many students that will watch this course will say 'Your pronunciation is bad', but, in these lectures I focused on the content and the information more than pronunciation.

I will listen to any criticize from students on the content and even pronunciation, in order to have a better courses later which will be on other and different topics.

After all I would like from students to tell me if my way of explanation is good for later courses ?

My name is Ahmed Muhammed and I am a programmer, I've come to Udemy to make simple and informative courses that anyone can easily understand. I will try to give you the information as possible. I will record courses for Programming, and the information will be from different resources; books, videos, and even blogs. The idea is to make courses simple and unclouded with useless information.
