Good morning everyone, I would to get help regarding a project i need to do about arithmetic and parity functions.

I have tried to start the research but I dont get what I'm looking for, if anyone knows where to get help or wants to help please do I'm desperate.

 

We'll need more information, I think. Are you wanting to do some math with gates, addition and subtraction? Two's Compliment is a good search phrase, along with a full adder.
