Hexadecimal(Binary)
Well, I'm pretty sure most of you have heard of Hexadecimal.
Basically Hexadecimal is a simpler form of substituting for binary numbers...It acts as variables in which:
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
Also you need to know that in Hex unlike binary which uses octets hex uses a 4 bit arrangement.(XXXX)
The Number Place Value is as follows:
x x x x
^^^^
8 4 2 1
So 1111 = 15 = F because:
8+4=12+2=14+1=15 Basically which ever place holder is turned on you add it, if it's off you don't add it so:
0011 = 3 because:
0+0+2+1=3
This is very easy to understand, if you don't understand any part please tell me.
