[Year 12 SofDev] More fun

[Kevork Krozian]

Hi Folks,

 Why stop there ? Investigate how arithmetic happens at the bit level as far 
as hardware required.
Build a half adder and a full adder building to a 4 bit adder and study the 
processing behind it .... rewind to the IT Systems course circa 1990.
