Number Systems and Conversions

This comprehensive page introduces the fundamental concepts of different number bases and their conversions. The content focuses on three main number systems: decimal (base 10), binary (base 2), and hexadecimal (base 16).

Definition: Base 10 system uses ten symbols (0-9), système binaire uses two symbols (0,1), and hexadecimal system uses sixteen symbols (0-9, A-F).

Highlight: Understanding binary numbers up to 15 is essential for effective number system manipulation.

Example: Binary representation of numbers 0-15: 0 = 0 1 = 1 2 = 10 3 = 11 4 = 100 5 = 101 6 = 110 7 = 111 8 = 1000 9 = 1001 10 = 1010 11 = 1011 12 = 1100 13 = 1101 14 = 1110 15 = 1111

Vocabulary:

• Convertir base 2 en base 10: Converting from binary to decimal
• Écriture en base 10: Writing numbers in decimal form
• Tableau binaire: Binary table for conversion
• Code binaire: Binary representation of numbers
