Among the class of adders also other logic units are listed, those that subtract, multiply or divide two numbers. Because in essence, the four basic arithmetic operations can all be replaced by the adding operation.
However, there are a wide variety of adders. Because you can build adder working with whole numbers, negative numbers or ever more complicated systems. Moreover, it is for all adder of very large binary numbers a challenge to produce the result as quickly as possible.
In this first part you learn how to set up the different adders, subtractors, etc.. In 16 experiments you build adders from logic gates. Thereby you improve gradually your adder.
In the second part (Go on...) you are working in another 6 experiments with pre-programmed adder IC's.
Let's go...and have fun...
