@juicifer ..T + ACAB (just A1Z26 conversion) features (X + I) = TA(XI)CAB, where "pound" here is the currency and not the weight (since the thing being measured here is the fare).
(Maybe it is specifically here where we are all used to puzzles that encode things that way without any explicit indication. But if I saw that in a newspaper crossword I'd be pretty shocked.)
I think I should have used the other justification: Wikipedia says that ACAB is a political slogan ("All Cops Are B*stards") which is sometimes rendered by its users as 1312
@GarethMcCaughan 1312 is fairly common as a stand-in for ACAB
I'd also be shocked if I saw it in a newspaper crossword but mostly because I don't think most newspapers would want to associate themselves with a particular side one way or another
The picture depicts a real traffic sign painted in South Africa.
It was intended to be an official traffic sign - but the painter, being unfamiliar with them, painted this according to the brief he was given.
What does the road sign represent?
What was the brief?
What language was this likely to...
I've been bored during our math classes at high school-so I decided to create my own math question. I've been brewing on it for a while-but I haven't gotten an answer. Probably just my tired brain telling me to stop, but I really want an answer and the working out.
If anyone wants the question it is: You have the numbers from 1-100 listed down. How many numbers do you have to remove from the list so that the remaining product of the numbers has a remainder of 4 when divided by 5? What are the numbers?
For a while I was writing an answer to the meta post about forcing people to upvote questions, thinking it was [Berkson's Paradox](https://en.wikipedia.org/wiki/Berkson%27s_paradox) and I even made a [SEDE query](https://data.stackexchange.com/puzzling/query/1611302/questions-vs-total-answer-score) but I found that there is a correlation
Ah, I hadn't realised that 1312 was a somewhat-standard abbreviation for ACAB-as-slogan. I retract my objection.
Stevo: obviously you need to remove all the multiples of 5. (There are 20 of these.) What's left then is 1,2,3,4 / 6,7,8,9 / ... / 96,97,98,99. Each of these 20 groups of 4 numbers has the same product modulo 5, namely 24 or, equivalently, 4 or, equivalently, -1. So the product of all the numbers from 1 to 100 that aren't multiples of 5 is 1 mod 5 (i.e., leaves a remainder of 1 when divided by 5). Now you can make the product be 4 mod 5 by removing any single number that's 4 mod 5.
(Such as, for instance, 4 itself.)
So the number of numbers you need to remove is 21. You can't do it with 20 or fewer because all the multiples of 5 has to go and that's 20 numbers and just removing those leaves a product that's 1 mod 5. You can do it with just 21 because removing the multiples of 5 along with 4 will do the job.

@AncientSwordRage Could you be more explicit? I am not sure (1) exactly what the plot shows (seems to be two separate scatterplots of a question's score against ... something else, and it seems like there are some regression lines drawn but I can't actually see them), (2) exactly what correlation you're saying you've found, (3) what exactly you're drawing attention to in the bottom left corner, or (4) what significance you find to #2 and #3. I think the answer to 2 and 3 may be [...continues]
... that you're saying that for bad questions there's a tendency for worse ones to have higher answer-scores, or something, but I'm not very sure.
(My apologies if that all sounds confrontational. It isn't meant to -- I'm curious rather than disbelieving -- but it's difficult to ask that sort of question without sounding like it's criticism masquerading as enquiry.)
@GarethMcCaughan Yeah I sort of gave up on the answer but wanted to share my graph and because I lost motivation I didn't explain very well
the data series are labeled, but the blue (occupying the 'lower diagonal') is the score of the highest scoring answer for that question (so a question at -10, with several answers at 0 but one at +10 will show at {-10, 10}), the orange is the total score of a question and all answers on it (so a question at -10, with several answers at 0 but one at +10 will show at {-10, 0})
if you look at the circled area it looks like there might a slight uptick of highly upvoted answers on low voted questions, but overall it looks like a linear trend up
That is, Good Questions get Good answers, so long as the question is positively upvoted
@GarethMcCaughan I suspect this is the case because those answers have an element of "Here's where you went wrong in your question" to them which people agree with and upvote.
In each puzzle, fill the circles with the numbers 1, 2, 3, ... n, where n is the number of circles in such a way that consecutive numbers are NOT in circles that are joined by a line.
