Answer from the amazing 3 bit adder! A bit hard to see but click on for a larger version. LEDs ABC are showing 101 - which is 5, and DEF are showing 011 or 3 in decimal. What is 3 + 5? Well check to the right WXYZ is showing 1000 - also known as 8... ! Amazing! (Actually for those in the known this is the carry bit - but anyways). 

A three bit adder using one half adder and two full adders. Built by two students in TEJ4 using XOR and AND gates.
