3+3 doesn’t show 6

+3
−0

I have a problem which I don’t understand how to solve. I have this 2-bit adder, but when I select A1AO to be (11)2 3 and B1BO to be (11)2 3 and run it on Logisim it doesn’t show me 6. Instead it shows me 4.

How can I fix it?

Rather than drawing these by hand all the time, consider using a schematics editor. There's plenty of free ones out there, like https://www.digikey.com/en/resources/design-tools/schemeit. Or https://www.falstad.com/circuit/ which also serves as a simulator - you can run and troubleshoot digital logic for example.
