Guessing the 3 outputs are less than, equal or greater than.

If you do not upload the .png file I doubt anyone will help with your school work. I went to look but my browser would not show it and I will not open the connections. And you did not show any effort or your location when you signed up. Sad to say I think you live in the US.

What is your teachers email address?

this is my effort to solve it

this is the algorithm:

it looks like a maze
i dont know even where to start looking

i cant understand this circuit
i tried to run with pen and paper on it
but i cant the logic behind it

if i put A3=B3=1 then it gives me 0 on then the E output
which represents if the two numbers are equal

thats odd
