I thought of this puzzle as almost unapproachable initially, then I read the comments, and someone said the word parity, this was a really beautiful puzzle when I realized that!

parity produced after adding and subtracting numbers is key to this puzzle

That was a nice steady challenge. Once I started asking the right questions (about parity) it flowed smoothly! Thanks for setting a puzzle with lots of arithmetic.

idk, maybe people don't like this puzzle or maybe they find the break in very hard. I could give a hint that make the puzzle a lot easier.

Very nice! Hard to get a break-in, but after getting some digits, it became smooth. Thank you
