Unsolvable. You can't just make a hanjie, you have to make it logical and solvable.

Stop making puzzles without checking them. You have made so many puzzles and most of them are completely illogical.
These are just the worst.

If you know the formula, you can guess it, but it's not logical.

The formula for anyone who wants is A2 +B2 = C2 (letters on the bottom five rows the numbers on the top five)

Complete guess work... couldn't have completed without the hint! Thanks @Hjaw123.

The 2s are completely in the top 5 rows, solve the one in the last 3 columns, and figure out where you can fit two more of those, then the bottom half will be logically solvable.
