Cambridge IGCSE Computer Science helps learners develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. They apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. Learners also develop a range of technical skills, and the ability to effectively test and evaluate computing solutions.

Studying Cambridge IGCSE Computer Science helps learners appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to Cambridge International AS & A Level and is valuable for other areas of study and everyday life.

Sir this is really useful and helpful and all and I appreciate the explanation, but I have a small question. How come in this part of the video (8:21), why is 12/2=6 how is there a remainder of 1, but when you did 6/2=3 and there is no remainder? Same with 3/2=1 but there isn't a remainder I am confused.
