Hexadecimal Number System

- The hexadecimal number system has 16 symbols:  

  - Digits 0 to 9  

  - Letters A to F (where A = 10, B = 11, … F = 15)  

- It is a positional value system, meaning each digit’s value depends on its position and is expressed in powers of 16.  

Decimal Conversion Rule  

- The decimal equivalent of any hexadecimal number is the sum of the product of each digit with its positional value.  

Example  

27FB = (2 x 16^3) + (7 x 16^2) + (15 x 16^1) + (10 x 16^0)

= 8192 + 1792 + 240 + 10 = 10234
