I first divide the number by 2 and check for remainder, then divide the results
(without remainder) by 2 again until you reach zero.. and so on.

2. ***** DECIMAL -> HEX *****
Now converting the decimal 3295 to HEX. As we already found it's binary it is easy
to convert to hex if we know the upper table by heart. Here we go!

110011011111b -> 1100 1101 1111 -> C D F

From here we have:

3295d == 110011011111b == 0CDFh

3. ***** HEX -> BINARY *****
Take number DEAD as an example
D = 1101
E = 1110
A = 1010
D = 1101

DEADh = 1101 1110 1010 1101b

Using the upper table we simply convert them.

4. ***** BINARY -> HEX *****
Take number 1010 1101 1110 1111b as an example

From the upper table:
0ADEFh

5. ***** BINARY -> DECIMAL *****
Take number 1101b as an example

1*(2^3) + 1*(2^2) + 0*(2^1) + 1*(2^0) == 13

First number 1

1 * (2^3)

Second number 1

1 * (2^2)

Third number 0

0 * (2^1)

Fourth number 1

1*(2^0)

Equals to 13.

6. ***** HEX -> DECIMAL *****
To convert hex to decimal, we first need to convert hex to binary and then
use the binary to decimal technique. Pretty easy huh :) Let's get going

Take number FEEDh as an example. This number converted to binary

1111 1110 1110 1101b

We will use the previous technique to convert binary to decimal.

This is a bigger number so WATCH what you're doing
