I could use some help knowing what the basic programming should look like
I semi understand binary.
In binary if you have 1011 its calculate under numatic values 8 4 2 and 1
1011
8421
--------
8021 8+0+2+1= 11 Which equals B in hex'= 1011
1010
8421 8+0+2+0=10 =A=1010
--------
8020
1111=F
But I dont understand how to start programing functions?
