Since you're looking for a simple article about "What is 'adder'", you've found the right place.

And the quick answer isβ¦

A circuit in which two or more signals are combined to give an output-signal amplitude that is proportional to the sum of the input-signal amplitudes.

As the name suggests, Adder is used to add binary numbers.

Adder circuit is basically a combinational logic circuit.

It is a memory less circuit and performs an operation assigned to it logically by a Boolean expression.

I have selected a few questions and answers to help you understand it:

What are the different types of adder designs...

Other adder designs include the carry-select adder, conditional sum adder, carry-skip adder, and carry-complete adder. If an adding circuit is to compute the sum of three or more numbers, it can be advantageous to not propagate the carry result. Instead, three-input adder are used, generating two results: a sum and a carry.
