machine language to assembly language

everyone say start with basics learn some basic things
so my another effort for learning about micro controller
I know about basic gates like AND, NOT and OR,
we can make following circuits with help of basic gates
Addition
Subtraction
Division
Multiplication
Logical AND
Shift Left
Shift Right

suppose we want to add two 8 bit number
we have to implement 8 bit adder

example 6+ 2 =8
00000110
+00000010
------------
00001000
...

so we can develop many circuit
Addition
Subtraction...
