Hexadecimal is used whenever we want to notate a binary value because each hex digit maps directly with each 4 bit nybble (half a byte). A 64-bit binary value can therefore be… reduced to a more concise 16-digit hex value. (MORE)

Normally, numbers are based on the base 10 system. This means there are ten symbols (numbers): 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. For numbers greater than 9, we use a combinati…on of symbols. The first digit specifies how many ones, the second digit (to the left) specifies how many tens, and so on..
In the hexadecimal system, there are sixteen symbols, because it is a base 16 system. The symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, and f. For numbers greater than f (equivalent to 15 in base 10), a combination of symbols is used. The first digit specifies how many ones, but the second digit (to the left) specifies how many sixteens. Ten in the hexadecimal system means one sixteen and no ones. In base 10, it would just be 16..
In HTML and CSS, hexadecimals are used to define colors and to insert symbols. (MORE)

If the above is decimal then in hexadecimal it is 2964492C2. If it is binary then in hexadecimal it is 7DA. If it is octal then in hexadecimal it is 49241208.

The word hexadecimal is composed of hexa- , derived from the Greek ÎÎ¾ (hex) for "six", and -decimal , derived from the Latin for "tenth". - from wiki hexadecima…l (also called base 16 or hex ) is a method of representing numbers using 16 unique symbols. The decimal nurerical system uses ten symbols 012345678 and 9 to represent numbers. Hexadecimal adds ABCDE and F to these to give 16 symbols with A representing ten and so on. (MORE)

In decimal it would 2784. In octal it would be 5340. In binary it would be 101011100000.

If you mean using the programming language, it'll do it automagically, for example, if you have in C: int a = 0x389; int b = 0x7A8; int c = a + b; .
then c will conta…in 0xB31 (in hexadecimal) - to display the value you would use: printf("a + b = %X + %X = %X = c\n", a, b, c); .
You can also convert to hexadecimal (for display) directly, for example: printf("0x%x + 0x%x = 0x%x\n", 127, 207, 127 + 207); .
which will display the sum in hex: 0x7f + 0xcf = 0x14e .
Hex is only a convenient way to display the numbers to humans. .
If you mean manually, yourself, then exactly the same way that you add in any other base. Start at the right hand end, add the digits together and when it becomes greater than the highest digit that can be stored in a single digit, subtract multiples of the base, write the remaining digit in the answer and the number of multiples of the base subtracted is added as a carry to the next digit sum to the left. With hexadecimal, just remember that: 0x8 + 1 = 0x9 0x9 + 1 = 0xA 0xA + 1 = 0xB 0xB + 1 = 0xC 0xC + 1 = 0xD 0xD + 1 = 0xE 0xE + 1 = 0xF 0xF + 1 = 0x10 A trick to thinking in hexadecimal is to remember that 8 is 1 / 2 of 16 and think of the digits above 7 as (8 + [0-7]), that is: 0x8 = (8 + 0), 0x9 = (8 + 1), 0xA = (8 + 2), 0xB = (8 + 3) 0xC = (8 + 4), 0xD = (8 + 5), 0xE = (8 + 6), 0xF = (8 + 7) and remembering that 0x8 + 0x8 = 0x10. Example: 0x389 + 0x7A8 = 0xB31 0x9 + 0x8 (= 8 + 1 + 8 = 0x10 + 1) = 0x11 = 0x1 carry 1 0x8 + 0xA + carry 1 (= 8 + 8 + 2 + 1 = 0x10 + 3) = 0x13 = 0x3 carry 1 0x3 + 0x7 + carry 1 (= 8 + 3) = 0xB If you can't think using the fifteen single digits, work in decimal remembering the conversions: 0xA = 10 0xB = 11 0xC = 12 0xD = 13 0xE = 14 0xF = 15 For example the second addition above becomes: 0x8 + 0xA + carry 1 = 8 + 10 + 1 = 19 (= 16 + 3 = 0x10 + 3) = 0x13 = 0x3 carry 1 (MORE)

That depends what you want to "do" with the hexadecimals - add, multiply, compare, etc. The first thing you would need to do is learn how it is defined.
