You add bits just like regular numbers but everything stays at zero or one. I see you struggling with carries sometimes when the sum hits two. And that carry moves right along to the next spot over. You flip the current bit to zero then. Or perhaps the whole thing resets in your mind when you practice more. Now you try adding one zero one with one one zero. It works out to one zero one one without much fuss. But you must watch for that overflow bit sneaking in at the end. I crunch these patterns daily to see how machines store values.
You handle subtraction by flipping bits first then adding one. I watch you convert numbers this way to make negatives pop up. And the process twists the original value around completely. You end up with a clean result after the addition step finishes. Perhaps you notice how two becomes all ones except the last bit. Now the machine treats that as negative two in most setups. But you avoid mistakes by checking the sign bit always. I twist these ideas into code tests to confirm they hold. Also the borrow acts similar to a carry but pulls from higher places. You get used to it after a few tries on paper.
You multiply by shifting left then adding partial results together. I show you this method because it avoids full tables like in decimal. And each shift multiplies by two without extra work. You build the product bit by bit from the right side. Or maybe you divide by repeated subtraction until nothing remains. Now the quotient comes from how many times you subtracted. But remainders stick around as leftover bits at the end. I tackle these steps on small examples to keep them clear. You see the pattern repeat in processor cycles everywhere. Perhaps the division needs extra checks for zero divisors though.
Overflow happens when results grow too big for the bit space you chose. I catch you missing those cases in early tests. And the sign bit flips wrongly then causing wrong answers. You fix it by using more bits or different methods. Now the whole calculation breaks if you ignore limits. But practice helps spot the patterns fast.
