That's a good point about showing work. I originally opted to avoid having it show work for brevity's sake, but it's possible that by "showing work" ChatGPT is storing enough context to compute the answer. So, I asked it to "limit work on each bit to a single line." which a human with understanding of the rules of addition would be more than capable of. The result (below) is still wrong :) Sure, let's add the two binary numbers you provided, keeping each bit operation to a single line. 10011111110100011100011011110010 + 00111010100101000100000101111011 Starting from the least significant bit: 1. 0 + 1 = 1 2. 1 + 0 = 1 3. 0 + 1 = 1 4. 0 + 0 + 1 (carry from step 3) = 1 5. 1 + 1 = 0, with 1 carry. 6. 1 + 0 + 1 (carry from step 5) = 0, with 1 carry. 7. 0 + 0 + 1 (carry from step 6) = 1 8. 1 + 1 = 0, with 1 carry. 9. 1 + 0 + 1 (carry from step 8) = 0, with 1 carry. 10. 0 + 0 + 1 (carry from step 9) = 1 11. 0 + 1 = 1 12. 1 + 0 = 1 13. 1 + 1 = 0, with 1 carry. 14. 1 + 0 + 1 (carry from step 13) = 0, with 1 carry. 15. 0 + 1 + 1 (carry from step 14) = 0, with 1 carry. 16. 0 + 0 + 1 (carry from step 15) = 1 17. 1 + 1 = 0, with 1 carry. 18. 1 + 0 + 1 (carry from step 17) = 0, with 1 carry. 19. 1 + 1 + 1 (carry from step 18) = 1, with 1 carry. 20. 0 + 0 + 1 (carry from step 19) = 1 21. 0 + 1 = 1 22. 1 + 0 = 1 23. 0 + 0 = 0 24. 1 + 1 = 0, with 1 carry. 25. 0 + 0 + 1 (carry from step 24) = 1 26. 0 + 1 = 1 27. 1 + 0 = 1 28. 0 + 0 = 0 29. 1 + 1 = 0, with 1 carry. 30. 1 + 0 + 1 (carry from step 29) = 0, with 1 carry. 31. 1 + 1 + 1 (carry from step 30) = 1, with 1 carry. 32. 0 + 0 + 1 (carry from step 31) = 1 So, the result of the binary addition is: 11011001000010100010001110101101
