Hexidecimals; A beginners Guide

Ok, hexidecimals are simple to learn. Hex coding is compiled of 15 base numbers:
Binary / Hex value
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
1000 = 8
1001 = 9

NOW here comes the tricky part, The hex value is acctually 1 followed by the letter, for example, 1010 = 1A, not 10.

Binary/Hex Value = Letter
1010 = 10 = A
1011 = 11 = B
1100 = 12 = C
1101 = 13 = D
1110 = 14 = E
1111 = 15 = F

NOW, After 15, hex numbers begin to get complex. Hex values are in binary form, and often fal into the same catagoruy as RAM, such as 32Mb, 64Mb, 128 Mb, etc... like so:

l 128 l 64 l 32 l 16 l 8 l 4 l 2 l 1 l

The number 30 would look like this:

00011110

Or like this in the chart

l 128 l 64 l 32 l 16 l 8 l 4 l 2 l 1 l
l 0 l 0 l 0 l 1 l 1 l 1 l 1 l 0 l

Now, these numbers (128, 64, 32, 16, 8, 4, 2, and 1) are called BITs (or some refer to them as bit rates), ranging from highest to lowest, left to right, respectivly.

Now, symbols. Symbols are a diffrent story. They are as follows:

58 = 00111010 = :
59 = 00111011 = ;
60 = 00111100 = <
61 = 00111101 = =
62 = 00111110 = >
63 = 00111111 = ?
64 = 01000000 = @

Do the math - Hex is basically encoded binary. When your binary number is present, you can use it for math! so, lets work on a problem.

Now, I have 00001111 and 00000011. Lets convert that to regular math.
\/ \/
15 3
\/
15/3 (00001111/00000011 in binary)
\/
5
\/
00000101

Same with +/-

00010000
-00000100
----------
00001100

-translates into-

16
-4
---
12

Now, ill be back tommrow, i have some things to do. Ill update my "lesson" ( lol ) tommrow

Haha, iv a test on this stuff tomorrow in college!

Lemme know how you do

Just came out of the test there now, wasnt too bad, never wrote so much 1's and 0s in my life!

Happy with it though!
