Understanding Number Systems

The video explores the evolution of counting from early humans to modern number systems. It explains the base 10 decimal system, highlighting its reliance on place value and the use of digits 0-9. The video then introduces the binary system, essential for computing, and explains how it uses only two symbols, 0 and 1, to represent numbers. The video emphasizes the importance of understanding different number systems and their applications.
