TOPIC 2.1.1
Hexadecimal Number System

Hexadecimal is another number system that works exactly like the decimal and binary number systems, except that it is based on sixteens. The hexadecimal also can be used to represent the same values as the decimal and binary number systems. Just like the decimal number system represents a power of 10, each hexidecimal number represents a power of 16. To represent the decimal numbers 10 through 15, hexadecimal uses the letters A through F, respectively. Consider the number 1132. This number represents (1 x 4096) + (1 x 256) + (3 x 16) + (2 x 1) = 4402, and 1 0001 0011 0010 in binary. Another example is shown below.
