My first project on this site!

this 4 bit adder is fully decimal, that means the number you input is decimal and the answer will also be in decimal. 

The circuit consists of a decimal-to-binary converter, an 4 bit adder and a binary-to-decimal converter.

The circuit is made without sub-circuits.

To use the adder, click any number you want on the left and right side of the plus. The answer will appear on the right side, in decimal and binary.
