Half Adder Let’s apply switching algebra to the design of a half adder, a core circuit in CPUs. A half adder takes two binary inputs and generates two outputs.

The output of the half-adder is a result of 0 or 1 and a carry of 0 or 1. Additional circuits shift the operation to the next binary digit on the left until the entire number has been added.

As a key building block, the half adder is used to construct more advanced computational circuits and is in high demand in information technology. 18 A half subtractor can perform a subtraction of ...

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit… ...
