Definition of Hexadecimal Number System.

A hexadecimal number system is a base-16 number system,

which means that it uses 16 different symbols to represent

numbers. These symbols are the digits 0 through 9 and the

letters A through F. The hexadecimal number system is often

used in computer programming because it is a convenient way

to represent large numbers in a compact form.

Equivalent Hexadecimal and Decimal Numbers.

To convert a hexadecimal number to a decimal number,

you can use the following steps:

1. Multiply each hexadecimal digit by its corresponding

power of 16.

2. Add up the results of step 1.

For example, to convert the hexadecimal number 1A to a

decimal number, you would do the following:

1. Multiply 1 by 16^1 = 16.

2. Multiply A by 16^0 = 10.

3. Add 16 and 10 to get 26.

Therefore, the hexadecimal number 1A is equivalent to

the decimal number 26.

To convert a decimal number to a hexadecimal number,

you can use the following steps:

1. Divide the decimal number by 16 repeatedly.

2. The remainders from step 1 are the hexadecimal

digits.
