An elementary electronic circuit in the arithmetic logic unit (ALU) of every CPU. The half-adder does nothing more than add one bit to another. GPUs have millions of half-adder equivalents. The output ...

As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA ...

We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

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 built ...
