binary is pretty darn simple:
there is 2 numbers in binary 1 and 0
0000 is 0
0001 is 1
and because there is only 2 number (1 and 0) you cannot type type 0002 so you type 0010 instead ect. ect. ect.
1 is 1, 10 is 2, 100 is 4, 1000 is 8, 10000 is 16, so if you want to type 54 you type 110100.
if you want to type something, you like text, then just remember that you should use unicode and the capitalised alphabet starts at 65, and the non capitalised alphabet starts at 97, and the last thing when you type test in binary you do it in a base-8 witch means you got 8 numbers (like this 00000000)
