Number Systems and Their Bases

The video tutorial explores the concept of multiples, focusing on the number five and its patterns. It delves into prime factorization, explaining how numbers can be broken down into their prime components. The decimal system, based on the number 10 due to human anatomy, is discussed, along with other number systems like binary and heximal, which are used in computing. The tutorial highlights the importance of understanding different bases in mathematics and their applications in everyday life.
