An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

I think I figured it out but I always second guess myself lol. I feel like getting it on the first try means I am way off.

Oh i see,
Its
solution
12
You add up the digits.
(7+2)+(9+9)=9+18=27
9+(4+5)=9+9=18
(1+8)+(3+9)=9+12=21
(2+1)+(3+6)=3+9=12
3+(2+8)=3+10=13
(1+3)+(2+1)=4+3=7
Yay

Oooh, sneaky but simple
Nice puzzle, at first you go "wtf last should be 8" but then I read the last sentence "not a typo" and took some minutes to crack it. If it wasn't for having seen a similar solution in a different puzzle I would have been completely lost and once you know the solution it's impossible to not see it. I can see how the author of the puzzle really liked it.
Dammit. I'm gonna have to stare at this for a few years now.
Got it. Nice puzzle.
First I figured out what was meant by the number 7 isn't a typo, by jumping to the wrong solution. Next I figured out the next idea was and it worked. No spoilers ༼ᕗຈل͜ຈ༽ᕗ
Got it! Really cool puzzle. I used to enjoy solving puzzles like this, but nowadays I don't spend time in that.
I remember doing decision trees at Uni, and saw it immediately. Glad you got there OP.
Fun puzzle
Being real, if this post hadn't made it clear that the solution was non obvious, I likely would have given up before getting it, just because my chicken is being more interesting than usual.
But, knowing that there was a "trick" to it, meaning that it takes some lateral thinking, I didn't take my usual approach to number puzzles, which means it only took one look at the upper left for the likely solution to be visible. Then it was just running down and testing with the rest, then plugging in for the solution.
No way in hell I would have had the patience for it when my baby bird is being a silly dinosaur without that front loading assumption the solution wouldn't be evident with a systematic approach. Oh, I'd have given it maybe fifteen minutes, but with a fuzzy butt in play, that would have been it
you what? lol
No, I who. dehumanization no good
What? You've never been distracted by a chicken before?

I love puzzles like this—the rule always seems obvious after you see it. It’s satisfying when something that sits in the back of your mind for years finally clicks.
Well, I got it correct with a guess based on a casual glance at what was there, not how the numbers actually relate or calculations based on rules or patterns.
Then I had to figure out how it actually worked.
Which was harder -- I wish I had kept scrolling.
Commenting for later (cheers OP)
I can give one hint if you want.
The solution reminded me of "Numerology". Which I am familiar with and probably why I was able to solve it in about a minute.
