A third one, this time with less gates.

Is there anything we can learn from?

No, it's just a fun little digital adder circuit.

Yikes thats a lot of gates, check out my 4 bit adder that a made a few months ago, it has a little more gates and works well.

For a 2 bit adder that's a lot

Seems like you overdid somthing because my 4 bit adder has a lot less gates actually

Here is my 4 bit adder: http://everycircuit.com/circuit/4993518027669504

And here is a 2 bit adder I just made for you. I made it as simple as I can. Hope you find this helpful! http://everycircuit.com/circuit/5627252417232896

If you cannot see links as i've heard before then just copy the link and paste it or just click on my profile and you'll see the circuits there.

Really quite amazing! I'm having trouble figuring out how it works, but it's absolutely amazing! My circuit basically has a set of gates that output positive if the inputs are in a specific pattern and no other pattern, this is repeated for every possible pattern, these sets then gets grouped together by OR gates which feed into the inputs of the 7 segment display. This method seems to use a LOT more gates.

So I understand how it works, but it's still quite amazing to me. I know that if you use XORs in the right way you can get almost anything to work without using nearly as many gates as one would otherwise use. The only trouble there is finding the right way to do it! That's my big problem, I'm not creative enough to figure these things out, also just a bit too lazy :)
