We need more information. My first guess was that this was binary addition, but then (1010)+ (1101)= 10111 and (1010)+ (0010)= 1100. Is this a "twos complement" notation?

Please DO NOT remove content from a post after help has been given. This devalues a topic, and voids the time given by the people trying to help.

This is prohibited by MHB rule #7:

Do not edit or delete questions after getting help. When a user edits or deletes a question after getting help, the context of the help is subverted and the thread becomes difficult for other members to follow. Moderators will close threads vandalised in this way, restore the deleted question, and the infract the offending member. The material posted on MHB is a body of knowledge that is a valuable resource for everyone. It is unacceptable to vandalize this resource. Note that a member who deletes a question after getting help casts suspicion of cheating upon themselves. Be careful what you post. Once you post a question or information, it will remain viewable to all members of the public - this includes all staff and students of the institute at which you may study - and may show up on search engines such as Google. It is good etiquette, if you mark your thread as [SOLVED], to post your solution so that others searching MHB will be able to see the solution, and not waste their search time.
I am using discretion here to not lock the topic nor issue an infraction, as I feel you were simply not aware of this policy, nor are you trying to cheat.

Lol HallsofIvy provided no help whatsoever. He was just asking me what I was actually asking. That's why i put solved. I figured out the problem by myself. But I will take note of this rule and adhere to it for the future.
